Description of the issue/feature this PR addresses:
Fixes an issue where the sale order reference computation was fetching the invoice journal based on the logged-in user's current company instead of the company associated with the specific payment provider or transaction context. This caused incorrect reference processing or errors in multi-company environments when a user was logged into one company but processing an order from another.

Current behavior before PR:
The function searches for the account.journal using self.company_id.id. Since self in this context (likely a payment provider or transaction record) might be evaluated under the active user's environment context, it fetched the journal from the user's currently active company (allowed_company_ids), disregarding the actual company related to the sale order or the transaction.

Desired behavior after PR is merged:
The invoice journal search uses the correct company context (e.g., order.company_id.id or the specific company linked to the payment record), ensuring that the sale order reference is processed using the appropriate journal from the correct company, regardless of which company the logged-in user is currently switched into.

Version:
----------
- 18.0+

Steps to reproduce:
-------------------
- Install `stock` module
- Enable `Storage Locations` from Inventory settings
- Create a tracked storable product with on-hand 8 units in `Shelf 1`
- Create Delivery 1 for 5 units and click `Mark as To Do`
- Create Delivery 2 for 5 units and click `Mark as To Do`
- Verify reservations:
  - Delivery 1 reserves 5 units
  - Delivery 2 reserves remaining 3 units
- Relocate all 8 units from `Shelf 1` to `Shelf 2` using the `Relocate` action from `stock quant`
- Reopen both deliveries

Issue:
------
After relocating stock between internal locations, reservations are reassigned
in the wrong order:
- Delivery 2 becomes fully reserved with 5 units
- Delivery 1 is reduced to 3 reserved units

This incorrectly swaps the original reservation priority between deliveries.

Cause:
------
The relocation wizard starts from:
`stock.quant.relocate.action_relocate_quants()`
which calls `move_quants()`:
https://github.com/odoo/odoo/blob/d3eebbd1c27e8a039bb55cdf2a82d464e06ffa8c/addons/stock/wizard/stock_quant_relocate.py#L70

`move_quants()` validates an internal stock move through `_action_done()`:
https://github.com/odoo/odoo/blob/d3eebbd1c27e8a039bb55cdf2a82d464e06ffa8c/addons/stock/models/stock_quant.py#L1572

During validation, `_synchronize_quant()` moves the stock quantity from
`Shelf 1` to `Shelf 2`.

However, the already reserved delivery move lines still reference `Shelf 1`.
This temporarily makes the source quant negative (`available_qty < 0`),
triggering `_free_reservation()`:
https://github.com/odoo/odoo/blob/d3eebbd1c27e8a039bb55cdf2a82d464e06ffa8c/addons/stock/models/stock_move_line.py#L695-L700

Inside `_free_reservation()`, move lines are ordered using
`current_picking_first`:
https://github.com/odoo/odoo/blob/d3eebbd1c27e8a039bb55cdf2a82d464e06ffa8c/addons/stock/models/stock_move_line.py#L816-L821

Since both deliveries share the same scheduled date, the fallback ordering
uses `-cand.id`, causing Delivery 2 (higher id) to be processed before
Delivery 1 (lower id).

The reservation cleanup therefore happens in this order:
- Remove Delivery 2 reservation (3 qty)
- Remove Delivery 1 reservation (5 qty)

The corresponding moves are then added to `move_to_reassign`
in the same order:
`[Delivery 2, Delivery 1]`
https://github.com/odoo/odoo/blob/d3eebbd1c27e8a039bb55cdf2a82d464e06ffa8c/addons/stock/models/stock_move_line.py#L849

Later, `move_to_reassign._action_assign()` processes the moves in recordset
order:
- Delivery 2 reserves 5 units first
- Delivery 1 only gets the remaining 3 units

As a result, reservation priority is unintentionally reversed after relocation.

Fix:
----
Before calling `_action_assign()`, reverse `move_to_reassign` 

This ensures reassignment preserves the original reservation order:
- Delivery 1 is reassigned first and recovers 5 units
- Delivery 2 receives the remaining 3 units

The reservation state therefore remains consistent before and after
internal stock relocation.

Summary
=======

`_check_if_used_in_website_form`, the ondelete hook on
`ir.model.fields` that guards against deleting a field referenced by
a website form, performs poorly on realistic databases. It can take
multiple minutes to validate a single field deletion, blocking user
actions such as removing a Studio field.

This commit restricts the scan to columns that can actually contain
website form markup, bringing the hook from multi-minute to
sub-second without any loss of coverage.

The Problem
===========

Deleting any `ir.model.fields` record triggers this validation hook,
which must ensure the field is not referenced inside any website
form. The implementation iterates every stored HTML column returned
by `website._get_html_fields()` and runs one case-insensitive
`ILIKE '%data-model_name="<model>"%'` search per column against
`<model>.<html_field>`, then parses each match with `lxml` and
validates it with XPath.

Two root issues cause the multi-minute cost:

- **Unbounded scan surface**: all stored HTML columns are scanned
  (~95 on realistic databases), even though the vast majority of them
  declare `sanitize=True` and `sanitize_form=True` (the defaults).
  When both flags are True, `<form>` tags are stripped on write and
  the column can never physically contain website form markup.
- **Per-column `ILIKE` cost**: `ILIKE` on large TEXT/JSONB columns
  performs a sequential scan. A single large HTML column is enough
  to make the hook run for several minutes on its own.

Improvements
============

- Scan only columns that can actually contain forms:
  - `ir.ui.view.arch_db` , primary target; all website forms are
    stored there.
  - HTML fields whose sanitization either is disabled
    (`sanitize=False`, e.g. `blog.post.content`,
    `website.custom_code_head`) or explicitly allows forms
    (`sanitize_form=False`, e.g.
    `product.template.website_description`, `hr.job.description`,
    `event.event.description`). Any other HTML field strips `<form>`
    on write and will never contain a form.
- Batch searches: group the deleted fields by model once and emit a
  single `OR`-domain search per candidate column, instead of one
  search per (field, column) pair.
- Parse each returned record with `lxml` and validate with XPath
  directly. The `ILIKE` domain already filters out non-matching rows
  DB-side.

Benchmarks
==========

Profiled on a database containing ~95 stored HTML columns and ~5.2k
views. The hook was invoked read-only via
`field._check_if_used_in_website_form()` on a custom field.

| Metric                         |     Before |      After |
| :----------------------------- | ---------: | ---------: |
| Hook wall time                 |     ~444 s |    ~173 ms |
| HTML columns scanned           |         95 |          5 |
| SQL queries issued             |         96 |          6 |

Key results:

- Hook wall time reduced from multi-minute to sub-second
  (~2,570× faster on the profiled database).
- Scan surface reduced from ~95 columns to a handful (1 +
  the form-capable HTML fields installed on the database, typically
  under 10).

Steps to reproduce:
- Install Attendances and Time Off
- Create an internal user.
- Give the user: Attendances Officer access & No Time Off Officer/Manager rights
- Create an employee linked to the user.
- Configure the employee with a Flexible Working Schedule.
- Create and approve a Time Off request for the employee.
- Open: Attendances -> Gantt View
- Navigate to the month containing the employee's approved leave.

Issue:
- An access error is raised when opening a month that contains the employee's
  approved leave.

Cause:
- In `_handle_flexible_leave_interval`, the code accesses `leave.holiday_id`
  to read fields such as `request_unit_half`, `request_unit_hours`, and
  `request_hour_from/to` on the `hr.leave` model.
- When the current user has Attendances Officer rights but no Time Off
  access(rare cases), the ORM access check on `hr.leave` raises an AccessError,
  even though this read is purely for internal calendar computation and
  does not expose leave data to the user interface.
 
Fix:
- Added sudo() on holiday_id to access the employee's leave details
  and compute the work interval as expected.

## Issue
When trying to call `dt.replace` on a `datetime.time`, a TypeError is raised

```
File "/home/odoo/Documents/src/odoo/190/odoo/addons/base/models/ir_sequence.py", line 270, in _next
    return seq_date.with_context(ir_sequence_date_range=seq_date.date_from, ir_sequence_date=dt.replace(tzinfo=None))._next()
                                                                                             ^^^^^^^^^^^^^^^^^^^^^^^
TypeError: 'tzinfo' is an invalid keyword argument for replace()
```

## Steps to reproduce
1. Install *Accounting* (`accountant`)
2. Update the `account.payment` sequence:
    - Toggle *Use subsequences per date_range* and create a range
3. In Accounting > Customers > Payments, create a payment:
    - Payment Type: Receive
    - Customer: Any
    - Amount: Any
4. **A traceback appears**

## Cause
This error was introduced by https://github.com/odoo/odoo/commit/4b9dd7893f96.

The `AccountPayment._compute_name` method calls `_next_by_code` and passes a date as the `sequence_date`.

https://github.com/odoo/odoo/blob/337efb069f6cf2cb9478a970f075fd139c1e8e0a/addons/account/models/account_payment.py#L420-L422

In the `_next` method, the `dt` variable is set to that date (`datetime.date`), and calling the `.replace` method on that variable raises an error, as there's no tzinfo for `datetime.date`s.

Currently, an error will occur when user multi edits name of projects.

Steps to replicate:
- Install `project` and open projects.
- From the list view select multiple projects and edit their name.

Error:
```
File '/home/odoo/src/odoo/saas-19.3/addons/project/models/project_project.py', line 754, in write
    analytic_account_to_update.write({'name': self.name})

    raise ValueError('Expected singleton: %s' % self)
ValueError: Expected singleton: project.project(8, 9, 10)
```

Cause:
- As multiple records were changed at the moment, `self` had multiple recordsets and trying to access `self.name` [1] causes this error.

Solution:
- Avoided accessing `self.name` on a multi-recordset during multi-edit.
- Updated analytic account names using the name recieved in the vals.

**Steps to reproduce on a new db:**
(bug also reproducable on runbot but the impact 
is less easy to compute because of influence of other
existing companies)

- create a new company as company 2 and use the existing 
default company as company 1.
- create a warehouse for both company
- for both comp, in settings for the 'fiscal localization' set 
Package : Generic Chart of account, if not already set
(to have account journals).
- for both comp, in settings for inventory valuation set 
'periodic' and for periodic valuation set 'daily'

From company 1 : 
- create a storable product with standard price method and 
set a cost of 30
- set an onhand quantity of 1
if you navigate to 'inventory valuation' you'll see that : 
  - initial balance is 0
  - ending stock is 30 
  - the variation lines have a balance of 30
  - all of this is expected

From company 2 :
- change the cost of the product to 10
- set an onhand quantity of 1
if you navigate to 'inventory valuation' you'll see that : 
  - initial balance is 0
  - ending stock is 10 
  - the variation lines have a balance of 10
  - all of this is expected
 
From any company :
- navigate to 'scheduled actions' and select the action 
'Stock Account: Inventory Valuation Closing'
- click on 'Run Manually'
- navigate to 'inventory valuation'

**Current behavior:**
with company 1 selected :
  - the initial balance is now 30 
  - ending stock still 30
  - no variation lines
  - the initial balance was correctly increased by the closing entry

with company 2 selected: 
  - the initial balance is now 40
  - the ending stock is still 10
  - the variation lines credit 30 in stock valuation

In company 2 the closing entry debitted 40 in stock valuation 
instead of 10 which increased the initial balance to 40 instead of 10

If you open the journal items you'll find the closing amls have a 
balance of 40 instead of 10

**Cause of the issue:**
The _cron_post_stock_valuation() method 
calls action_close_stock_valuation() on both companies
https://github.com/odoo/odoo/blob/bfa39854e56da4bf23295d62f63d66973ad0d78e/addons/stock_account/models/res_company.py#L143-L144

This methods calls _action_close_stock_valuation
with a context modified with only self.env.company.ids
in 'allowed_company_ids'
https://github.com/odoo/odoo/blob/bfa39854e56da4bf23295d62f63d66973ad0d78e/addons/stock_account/models/res_company.py#L56

This is needed because inside stock_value() we use 
the total value of the product 
https://github.com/odoo/odoo/blob/bfa39854e56da4bf23295d62f63d66973ad0d78e/addons/stock_account/models/res_company.py#L92
which will be the sum of the values of the product 
for each company inside allowed_company_id
https://github.com/odoo/odoo/blob/bfa39854e56da4bf23295d62f63d66973ad0d78e/addons/stock_account/models/product.py#L274
So in case action_close_stock_valuation() was called from 
the 'generate entry' button from the inventory valuation view
we need only the main company selected to be in the
'allowed_company_ids' so that the inventory value is computed 
based only on this company (as is the accounting value).

The problem is that this does not work when calling the 
method from _cron_post_stock_valuation because then
there is no 'allowed_company_ids' in the context (because it was
called from _process_job() with a new env).
so self.env.company will be the company of the user 
which will be company 1.
https://github.com/odoo/odoo/blob/bfa39854e56da4bf23295d62f63d66973ad0d78e/odoo/orm/environments.py#L243

Therefore when _action_close_stock_valuation will be 
called on company 2, in the context, allowed_company_ids 
will be company 1. Then, when computing 'products', with_company() 
will add self (company 2) to the context.
https://github.com/odoo/odoo/blob/616e82d7b3a53b1facf481e783baed3e99393d3c/addons/stock_account/models/res_company.py#L151-L152
So stock_value will return the sum of the total_value 
of each product for company 1 and company 2 which is 40 (instead 
of 10 for just company 2)
https://github.com/odoo/odoo/blob/616e82d7b3a53b1facf481e783baed3e99393d3c/addons/stock_account/models/res_company.py#L242

We then create the closing accounting entry to match the 
accounting value with the stock value, which explains why 
the new initial accounting balance of company 2 is 40.

**fix:**
We set the context using self instead of self.env.companies
This makes more sense as both in the cron use case and 
the generate entry use case the stock value we want is the 
one of the company in self. 
- In cron use case, it's obvious as the method is called 
in a for loop on each company
- In the generate entry use case, self will also be the main 
company, because it's called, in actionGenerateEntry, 
on this.companyId 
https://github.com/odoo/odoo/blob/616e82d7b3a53b1facf481e783baed3e99393d3c/addons/stock_account/static/src/stock_valuation/controller.js#L75
which is computed based on the get_report_values
https://github.com/odoo/odoo/blob/616e82d7b3a53b1facf481e783baed3e99393d3c/addons/stock_account/static/src/stock_valuation/controller.js#L21

Which returns the main company
https://github.com/odoo/odoo/blob/616e82d7b3a53b1facf481e783baed3e99393d3c/addons/stock_account/report/stock_valuation_report.py#L29


Most importantly, this is also aligned with how the accounting 
values are computed.

**Description of the issue/feature this PR addresses:**

The `Product Reference Price` feature in `website_sale` cannot correctly handle products sold in large packs when the reference quantity requires a very small `base_unit_count`.

For example, a product sold as a `box of 10000` screws should be able to use `0.0001` as its `Base Unit Count`, so the reference price can be computed against the box quantity correctly.

**Current behavior before PR:**

`base_unit_count` uses the default float precision, so values with more than two decimal places are rounded in the product form.

When trying to set `Base Unit Count` to `0.0001`, the value is rounded to `0.00` / `0.01`, which makes the Product Reference Price computation incorrect.

Steps to reproduce:

1. Go to Settings > Website and enable Product Reference Price.
2. Create or open a product named `Screws`.
3. Set Sales Price to `$ 1.00`.
4. On the product form, set Base Unit Count to `0.0001`.
5. In Custom Unit of Measure, type `box of 10000` and press Create.

**Desired behavior after PR is merged:**

`base_unit_count` keeps high-precision values such as `0.0001`.

This allows `Product Reference Price` to correctly support large-pack scenarios, such as selling screws in a `box of 10000`, by storing `base_unit_count` with unlimited numeric precision.

**Description**
Opening the Budget Report from any budget record times out on databases
with significant data volume. The request to
`budget.report/formatted_read_grouping_sets` consistently times out,
making the Budget Report completely unusable.

**Root cause:**
`budget.report` is an SQL view that consists of 5 UNION ALL branches.
When the list view loads, the ORM translates the `budget_analytic_id`
domain into a WHERE clause on the outer query wrapping the full UNION
ALL subquery. PostgreSQL cannot push this filter through a UNION ALL as
it's a hard optimization barrier. It must fully materialize the subquery
regardless of which budget is being viewed.

**Fix:**
Override _search on budget.report to extract budget_analytic_id and
budget_line_id conditions from the incoming domain using the Domain API.
budget_line_id is rewritten as Domain('id', op, value) so _to_sql()
correctly emits bl.id in the raw SQL. The resulting domain is injected
in context under budget_line_domain and read in _get_bl_query,
_get_aal_query (base module), and _get_pol_query (purchase module) to
filter budget_line rows inside each branch's LEFT JOIN ON clause.
This also removes the budget_report_budget_line_ids context key from
budget_line._compute_all, unifying both filters under one mechanism.

## Issue
When trying to call `dt.replace` on a `datetime.time`, a TypeError is raised

```
File "/home/odoo/Documents/src/odoo/190/odoo/addons/base/models/ir_sequence.py", line 270, in _next
    return seq_date.with_context(ir_sequence_date_range=seq_date.date_from, ir_sequence_date=dt.replace(tzinfo=None))._next()
                                                                                             ^^^^^^^^^^^^^^^^^^^^^^^
TypeError: 'tzinfo' is an invalid keyword argument for replace()
```

## Steps to reproduce
1. Install *Accounting* (`accountant`)
2. Update the `account.payment` sequence:
    - Toggle *Use subsequences per date_range* and create a range
3. In Accounting > Customers > Payments, create a payment:
    - Payment Type: Receive
    - Customer: Any
    - Amount: Any
4. **A traceback appears**

## Cause
This error was introduced by https://github.com/odoo/odoo/commit/4b9dd7893f96.

The `AccountPayment._compute_name` method calls `_next_by_code` and passes a date as the `sequence_date`.

https://github.com/odoo/odoo/blob/337efb069f6cf2cb9478a970f075fd139c1e8e0a/addons/account/models/account_payment.py#L420-L422

In the `_next` method, the `dt` variable is set to that date (`datetime.date`), and calling the `.replace` method on that variable raises an error, as there's no tzinfo for `datetime.date`s.

**Description of the issue/feature this PR addresses:**

The `Product Reference Price` feature in `website_sale` cannot correctly handle products sold in large packs when the reference quantity requires a very small `base_unit_count`.

For example, a product sold as a `box of 10000` screws should be able to use `0.0001` as its `Base Unit Count`, so the reference price can be computed against the box quantity correctly.

**Current behavior before PR:**

`base_unit_count` uses the default float precision, so values with more than two decimal places are rounded in the product form.

When trying to set `Base Unit Count` to `0.0001`, the value is rounded to `0.00` / `0.01`, which makes the Product Reference Price computation incorrect.

Steps to reproduce:

1. Go to Settings > Website and enable Product Reference Price.
2. Create or open a product named `Screws`.
3. Set Sales Price to `$ 1.00`.
4. On the product form, set Base Unit Count to `0.0001`.
5. In Custom Unit of Measure, type `box of 10000` and press Create.

**Desired behavior after PR is merged:**

`base_unit_count` keeps high-precision values such as `0.0001`.

This allows `Product Reference Price` to correctly support large-pack scenarios, such as selling screws in a `box of 10000`, by storing `base_unit_count` with unlimited numeric precision.

Steps to reproduce
1. Set warehouse to 2-step incoming (Input → Stock)
2. Enable "Propagation of carrier" on the push rule (Input → Stock)
3. On the vendor, set "Purchase Orders Grouping" to "Always"
4. Create a storable product with the Buy route and that vendor
5. Create two sale orders for that product, each with a different delivery carrier
6. Confirm both sale orders → a single merged purchase order is created
7. Confirm the purchase order → a receipt (Vendors → Input) is created
8. Validate the receipt → ValueError: Expected singleton: delivery.carrier(1, 3)

Issue
In `_get_new_picking_values`, when the push rule fires to create the internal transfer (Input → Stock), the carrier is fetched from the referenced sale orders: carrier_id = self.reference_ids.sale_ids.carrier_id.id https://github.com/odoo/odoo/blob/5fb0c1f1460949043aa23ddbed09bdbfdc4a8482/addons/stock_delivery/models/stock_move.py#L45

Because both sale orders share the same merged receipt, the receipt move references both. When those SOs have different carriers, `self.reference_ids.sale_ids.carrier_id` returns a multi-record recordset and calling `.id` raises `ValueError: Expected singleton: delivery.carrier(1, 3)`.

When a Time Off Type is created, it inherits the country of the current company. If there are leaves or allocations created from this Time Off Type and the company's country is then changed, various parts of Time Off will throw access errors as the leaves and allocations are still tied to the former country. The goal of this PR is to constrain
the company country from being changed unless there are no such leaves or allocations.

**Steps to Reproduce on Runbot:**
1. Ensure the current company has a `country` set, e.g. "My Company (San Fransisco)" has country set to "United States". 
2. Access Time Off as Mitchell Admin.
3. Create a new Time Off Type, for simplicity's sake without a need for allocation or approval, ex: "Gone Fishing". Note this Time Off Type will have the `country` set to the company country by default. 
4. Take "Gone Fishing" time off. 
5. Change or set blank the company's `country` value. 
6. Ensure the record rules cache is flushed.
7. Try to access Time Off.

When opening a profile from the avatar card, the employee's company may
not be in the user's active companies. Until now this popped a confirmation
dialog that only let the user either activate the other company or cancel,
with no way to reach the still-accessible contact profile.

Replace the dialog with a less intrusive "View Profile" dropdown, shown
only when the employee's company is allowed but not active. It offers two
choices:

- Open Employee Profile (activates the company)
- Open Contact Profile (no company activation)

Activating an extra company widens the active-company scope for the whole
session, which is not always desirable, so keeping a non-mutating path to
the contact profile is useful. In every other case (no employee, company
already active, or company not allowed) the plain "View Profile" button is
unchanged.

This PR is one of many triggered by responses from Luxembourg auditors. See PR #113316 for a full list of these PRs.

As described in PR #117799, the \CustomerID and \SupplierID elements on \Transaction\Line elements is determined by a partner's `customer_rank` and `supplier_rank`.  This is a binary designation, one or the other.

The Luxembourg FAIA report requires that less than 30% of \Transaction\Line elements with payable accounts (class 6) can not have \SupplierID. The same applies for \Transaction\Line elements with receivable accounts (class 7) and the \CustomerID element.

TSB clarified that any partner on an receivable or payable line should be added to the Customer list or Supplier list respectively https://github.com/odoo/enterprise/pull/100749#issuecomment-3655127511. In addition, I verified that Luxembourg's analysis of four separate FAIA files (from ticket 5427296) aligns with this expectation. 

<img width="1322" height="690" alt="image" src="https://github.com/user-attachments/assets/1a82f99e-5b32-4dbb-96e1-1b25bab2629b" />

This commit adds partners to the \Supplier and \Customer lists if they have any payable or receivable lines, respectively. It also picks between the \CustomerID and \SupplierID based on a line's `account_type`. This logic is applied to `account_saft` and updates the other, country-specific SAFT reports where appropriate. 

It also retains the previous `customer_rank` and `supplier_rank` logic as a fallback for older XML reports and for accounts other than `asset_receivable` or `liability_payable`.

**Problem:**
On the /shop page, the "Fill" option in the web editor (cover/contain toggle on product card images) appears clickable but has no visible effect on the product thumbnails.

**Steps to reproduce:**
1. Install website_sale and open /shop.
2. Open the web editor and select the shop page.
3. Locate the "Fill" button group in the right panel (with the two svg icons).
4. Click the alternate option to switch between cover and contain.
5. Observe that the product card thumbnails do not change appearance.

**Current behavior:**
The toggle flips the `o_wsale_context_thumb_cover` class on the products table (and the activation of the `products_thumb_cover` view), but the product images keep rendering with `object-fit: contain` regardless of the toggle state.

**Expected behavior:**
The image fill mode follows the toggle:
- "cover" option active   → product image uses `object-fit: cover`
- "cover" option inactive → product image uses `object-fit: contain`

**Cause of the issue:**
The product image template renders the img with the `object-fit-contain` utility class, and the local SCSS rule declares
`.object-fit-contain { object-fit: contain !important; }`. The CSS variable `--o-wsale-card-thumb-fill-mode` (set to `cover` by `.o_wsale_context_thumb_cover`) does cascade down to the img, but the non-variable, `!important` rule on the utility class always wins, so the variable-driven rule
`object-fit: var(--o-wsale-card-thumb-fill-mode, contain)` is silently overridden and the toggle becomes inert.

**Fix:**
Making the `.object-fit-contain` rule read the same CSS variable lets the existing toggle mechanism take effect without changing any template or removing the utility class. Outside the `.o_wsale_context_thumb_cover` context the variable is undefined, so the `var(..., contain)` fallback preserves the prior `contain` behavior for any other consumer of the class. This keeps the change to a single SCSS line, with no XML touched and no other CSS class semantics altered.

PostgreSQL's `unaccent` function must be marked as `IMMUTABLE` before it can be used in a functional index.

The ORM usually handles this when the `unaccent` extension is missing and `odoo-bin` is started with the `--unaccent` flag during database creation.
However, it is also possible to start `odoo-bin` with an existing database where the `unaccent` extension is already installed, but the function was never marked as `IMMUTABLE`.

In that case, `unaccent` can still be used in conditions such as `WHERE` clauses, but it cannot be used in functional indexes.

`has_unaccent()` actually has three possible states:
```py
class FunctionStatus(IntEnum):
    MISSING = 0    # function is not present (falsy)
    PRESENT = 1    # function is present but not indexable (not immutable)
    INDEXABLE = 2  # function is present and indexable (immutable)
```
Therefore, checking only `if has_unaccent()` before creating an index using `unaccent` is not enough. The index should only be created when `has_unaccent()` returns `FunctionStatus.INDEXABLE`.

Steps:
- Install an Odoo 17.0 database with the Indian Payroll module and demo data.
- Upgrade the database to 18.0.

Issue:
- The Indian payroll demo data creates leave allocations and approves them through an XML function call.
- During a fresh installation, demo files are loaded in 'init' mode, so the approval function is executed and the allocations move from 'confirm' to 'validate'.
- However, during a 17.0 >>> 18.0 upgrade, demo files are loaded in 'update' mode. Odoo automatically loads demo files with 'noupdate=True' from the load_demo() >> load_data() function:
- This value is passed to the XML importer and becomes the default noupdate state for the file. Since the demo XML file does not explicitly override this value, the function tag uses 'noupdate=True'.
- When the XML parser reaches the approval function, _tag_function() skips its execution because of noupdate = 'True' and mode = 'update' condition.
- As a result, the approval function is not executed during the upgrade and the leave allocations remain in 'confirm' state. Subsequent demo payroll data expects validated allocations and fails during loading.

Fix:
- Explicitly set 'noupdate=0' on the demo XML file. This overrides the default 'noupdate=True' value applied to demo files, making the parser evaluate the section with 'noupdate=False'.
- As a result, '_tag_function()' executes the approval method during upgrades, the demo leave allocations are validated in both fresh/new db installations and 17.0 >>> 18.0 upgrade scenarios.

**Steps to Reproduce**

1. Create a database on v19.3.
2. Install `hr` and `hr_payroll`.
3. Create or log in as a user who only has access rights for the Employee app (`hr`) and no Payroll access.
4. Go to **Employees → Configuration → Employee → Employee Types**. Opening the Employee Types menu raises the following error:

```python
You do not have enough rights to access the field "employee_type_id" on
Employee Contract (hr.version). Please contact your system administrator.

Operation: read
User: 2
Groups: allowed for groups 'Payroll / Assistant'
```

**Issue Description:**

The field `employee_type_id` is defined in both modules with different group restrictions:

* In `hr/models/hr_version.py`, the field is restricted to **HR Managers**. [field](https://github.com/odoo/odoo/blob/f7e87637d5c47047ebffda0f3c929c25022c3f27/addons/hr/models/hr_version.py#L184)
* In `hr_payroll/models/hr_version.py`, the field is extended with the **Payroll / Assistant** group.
[field](https://github.com/odoo/enterprise/blob/acd831acd0f59f7b8c15bccfb6da0c3969fc3f6d/hr_payroll/models/hr_version.py#L41) When both modules are installed, access to `hr.version.employee_type_id` requires Payroll permissions.

In v19.3, PR #241780 introduced the `employee_count` [computation](https://github.com/odoo/odoo/blob/f7e87637d5c47047ebffda0f3c929c25022c3f27/addons/hr/models/hr_employee_type.py#L25) on `hr.employee.type`. During this computation, `_read_group()` is executed on `hr.employee` using the domain.

[pr] : https://github.com/odoo/odoo/pull/241780/changes

HR-only users (without hr_payroll.group_hr_payroll_user) cannot read the field, causing below traceback.

**Solution**

added `group_hr_manager` group to the field `employee_type_id` so both groups can view employee_type.

Currently, an error occurs when downloading the asset template.

**Steps to Reproduce:**
 - Install the `account_asset` module without demo data.
 - Go to `Accounting` > `Configuration` > `Accounting` > `Chart of Accounts`.
 - Open the `Fixed Assets` account, set a `Depreciation` value, and remove the `account code`.
 - Go to `Accounting` > `Accounting` > `Assets & Liabilities` > `Assets`.
 - Click `With our template` on the screen.

`TypeError: startswith first arg must be str or a tuple of str, not bool`

After this [recent commit], account codes became optional and can be removed. As a result, when 
the code is removed from the Fixed Assets account and when donloading the asset template, the 
system checks whether the account name starts with the account code [1]. Since the account 
code is `False`, it raises an error.

This commit ensures that the check is only performed when the account code exists; otherwise, 
the account name is used directly for the asset account.

Version:
- 19.0

Steps to reproduce:
- Install Attendances and Time Off
- Create an internal user.
- Give the user: Attendances Officer access & No Time Off Officer/Manager rights
- Create an employee linked to the user.
- Configure the employee with a Flexible Working Schedule.
- Create and approve a Time Off request for the employee.
- Open: Attendances -> Gantt View
- Navigate to the month containing the employee's approved leave.

Issue:
- An access error is raised when opening a month that contains the employee's
  approved leave.

Cause:
- In `_handle_flexible_leave_interval`, the code accesses `leave.holiday_id`
  to read fields such as `request_unit_half`, `request_unit_hours`, and
  `request_hour_from/to` on the `hr.leave` model.
- When the current user has Attendances Officer rights but no Time Off
  access(rare cases), the ORM access check on `hr.leave` raises an AccessError,
  even though this read is purely for internal calendar computation and
  does not expose leave data to the user interface.
 
Fix:
- Added sudo() on holiday_id to access the employee's leave details
  and compute the work interval as expected.

Currently, when a user without accounting permissions attempts to cancel a Manufacturing Order (MO), an Access Error is raised.

## Steps to produce:
- Install Manufacturing and Accounting with demo data.
- Users > Marc Demo > Remove Accounting Permissions and give Admin permissions for Manufacturing
- Login as Marc Demo
- Create an MO for` [D_0045_G] Stool (Green) `and try to cancel it.

## Observed Behavior:
Failed to read field mrp.workorder.employee_analytic_account_line_ids

## Root cause:
After PR [1], version 19.0 introduced access checks when reading many2many fields. As a result, if a user lacks read access to a model field, an access error is raised.

During cancellation, `action_cancel` [2] is called, and the error occurs when unlinking, since the user does not have read access to the account.analytic.line records the system throws an access error.

**Why does this error not occur in 19.3+?**
Commit [3] added `sudo` to allow cancellation of workorder

## Solution:
Manufacturing Administrators often need to cancel MOs and WOs, but granting them accounting rights solely for this purpose is not always necessary. A practical solution is to allow MO cancellation through sudo privileges, which can be achieved by backporting [3].

`formatLang` is applied at the report data level, converting floats into locale-formatted strings. These values are then used directly in arithmetic operations without normalization.

Fix:
Normalize values before computation by:
- Converting input to string
- Replacing locale-specific decimal separators (',' -> '.')
- Casting to float
- Falling back to 0 when value is None or empty

Issue
-----
There are 2 issues with USPS rest:

1. USPS packagings do not have their size UOM displayed. This leads to confusion as users input in inches but the dimensions are treated as feet.

2. USPS returns the same rate regardless of the package type.

Steps to reproduce
-----
- Set USPS up
	- Open the Package Type form > go to its' Dimensions tab

> Issue 1

- Set USPS up (domestic)
	- Select a `Domestic Rating Indicator` (eg LF - Flat Rate Box)
- Create a SO with some product
- Open the delivery widget and add a rate with USPS
	- Discard the changes
- Go to the delivery method and change the rating (eg SP - Single Piece)
- Go back to the SO
- Open the delivery widget and add a rate with USPS

> Issue 2, rate is the same as before

Issue 1

By default, there is no displayed UOM on the form because of

We can change this behaviour for USPS specifically as done in Envia

Issue 2
-----
In `usps_rest_rate_shipment`, we request rates for every package of the delivery, which we receive as lists. We then iterate over the list to find the rate matching the `mail_class`. The problem is that this only filters over whether the delivery is domestic or international. We don't filter based on the actual service selected on the carrier (`usps_domestic_rating_indicator` for domestic and `usps_international_rating_indicator` for international).

Module: l10n_it_pos

Steps to reproduce:
- In the POS settings, enable "Automatic Receipt Printing";
- Enable "ePos Printer" to make the "Skip Preview Screen" option appear;
- Disable "Skip Preview Screen";
- Disable "ePos Printer";
- Set up an Italian Fiscal Printer;
- Open a POS session and process a first order. Issue: After the first receipt, no other messages (price display, receipt, open register) are sent to the fiscal printer. A page reload is required.

Issue: After the first receipt, no other messages (price display, receipt, open register) are sent to the fiscal printer. A page reload is required.

Cause:
When "Automatic Receipt Printing" is true but "Skip Preview Screen" is false, a race condition occurs. `afterOrderValidation` triggers a print job while simultaneously transitioning to the `ReceiptScreen`. When the `ReceiptScreen` mounts, it triggers a second fiscal print job before the first has resolved. This creates a deadlock in `toHtml` of  `renderService`, permanently blocking the printer queue.

Solution:
Since the italian localisation sending the receipt to the fiscal printer is mandatory, the printing route is now tied to the "Skip Preview Screen" option.

[opw-5979212](https://www.odoo.com/odoo/project/49/tasks/5979212)

Steps to reproduce
------------------
1. Set a default tax on the "Cash Difference Gain" account (e.g. a 25%
   sales tax) -- required in some countries like Denmark (cf 5972690).
2. Open a PoS session, count more cash than expected at closing.
3. Try to close the session.

-> Error message shows up "The journal entry reached an invalid
state..." ... "The journal entry must always have exactly one journal
item involving the bank/cash account"

What's happening
----------------
PoS creates a bank statement line with the gain account as counterpart,
resulting in 2 lines: cash +10, gain -10. Since the gain account has a
default tax, `_sync_tax_lines` adds a tax line of -2.5 on top, which
makes the move unbalanced by 2.5. Then `_sync_unbalanced_lines` adds a
4th line to fix it, on the line returned by
`_get_automatic_balancing_account`, which is `journal.default_account_id`,
i.e. the cash account itself for a cash journal.

So we end up with 2 lines on that same cash account, which a bank
statement line move doesn't allow -> Error.

The fix
-------
In `_post_statement_difference`, precompute the base and tax split
ourselves and build the statement line's `line_ids` directly (e.g. for
+10 and a 25% tax: cash +10, gain -8, tax -2). The move is balanced
from creation, so `_sync_tax_lines` and `_sync_unbalanced_lines` don't
have to touch it.

Note that we force the tax computation to be in 'force_price_include'
mode, as the counted cash difference is a gross amount (physical money
in the drawer). This way the tax is always extracted from the cash
amount, regardless of how the tax is configured (included or excluded
in price). Same pattern is already used by `hr_expense` (cf
`hr_expense.models.account_move_line._compute_totals`).

Behavior before:
Adjusting physical inventory quantities for reserved packages takes time when linked to large delivery orders (e.g., 400+ lines). The user interface freezes, causing a poor warehouse user experience during stock counts.

Behavior after:
Inventory adjustments on reserved packages process faster. The UI remains responsive, and package records are updated instantly without performance degradation.

Root Cause:
When an inventory adjustment triggers '_free_reservation', it processes move lines sequentially. Inside this loop, Odoo recursively runs '_check_entire_pack()', forcing a full database evaluation of all 400+ delivery lines for every single line adjusted. This results in heavy, redundant processing.

Fix:
Used a context flag `bypass_entire_pack=True` to silence the '_check_entire_pack()' validation while looping through individual line adjustments. Once the loop completes, the package validation is called exactly once in batch for all affected pickings, preserving data integrity while eliminating redundant database queries.

Steps to Reproduce:
1. Have a product tracked by Lot and Package.
2. Have an open delivery order in Ready state (stock reserved) containing 400 or more lines of this product, one package per line.
3. Go to Inventory → Physical Inventory.
4. Set the counted quantity of any reserved bag to 0.
5. Click Apply.
6. Observe that the system takes time to process this single change.
7. Unreserve the delivery order.
8. Perform the same steps as mentioned above.
9. Inventory adjustment is much faster.

## The Problem
When grouping messages, the code was accumulating recordsets using the `|=` union operator inside a loop. Since each union call internally builds an `OrderedSet` over all previously accumulated IDs, the performance degraded quadratically relative to the number of document records. This caused bottlenecks on databases with large message volumes.

## The Solution
* Replaced the `|=` recordset accumulation with a plain Python dictionary of ordered sets to store IDs per operation, while keeping same behavior.
* Deferred the `browse()` call until after the loop is complete.
* Reduced the overall complexity from **$O(N^2)$** to **$O(N)$**.

---

## Benchmarks
*Tested on a customer database grouping by "Created By" and "Created On":*

| Record Count | Before | After | Improvement |
| :--- | :--- | :--- | :--- |
| **300k records** | 83.00s | **1.00s** | **-99%** |
| **30k records** | 0.60s | 0.25s | (Minor) |

**Note:** The performance gains become exponentially more significant as the record count grows.

**OPW-6123758**

Forward-Port-Of: odoo/odoo#260147

The translate button next to a translatable field saves the record before opening the translation dialog for its id. Since https://github.com/odoo/odoo/commit/a85ca9679e3855936afc66b034d05d75f672dd26 it saves record.model.root rather than the record itself. When the field belongs to a new record still edited inside an x2many, for example an answer added in the survey question popup, saving the root only saves the parent and the new line keeps no database id. The dialog then opens with the id set to false and calls update_field_translations on it, which builds WHERE id = false and the database rejects it with operator does not exist: integer = boolean.

Such a record gets no id of its own, and after a save and reload there is no reliable way to match the saved line back to the one that was clicked, so the dialog can never open for it. A canTranslate getter in TranslationButton returns false for a new record whose model root is another record, which is exactly a line still edited inside an x2many, and the template only renders the button when it is true. The variant in editable lists, where model.root is a list rather than a record, was handled in https://github.com/odoo/odoo/commit/cb34b318004c3ca9db755d8dbbad429609220df3.

Steps to reproduce:
1. Activate a second language in Settings > Translations > Languages
2. Open the Surveys app and create a survey
3. Add a question, then in the Answers tab add a line and type a value
4. Click the EN button next to the answer, fill the second language, and Save

=> RPC error operator does not exist: integer = boolean from WHERE id = false
