Currently, when a quotation is created from a repair order generated from a helpdesk ticket, 
the salesperson is not set on the quotation even if the customer has a salesperson assigned.

**Steps to Reproduce:**

 - Install `helpdesk_repair`.
 - Go to `Helpdesk` > `Configuration` > `Helpdesk Teams`.
 - Open a team recod and enable `Repairs`.
 - Create a `contact/customer` with a `salesperson` assigned.
 - Go to `Helpdesk`, create a ticket for that `customer`, and select the `helpdesk team` 
   configured above.
 - Click `Repair`, then click `Create Quotation`.
 - Open the quotation and check the `Salesperson` field in the `Other Info` tab.

**Current behavior:**
The Salesperson field on the quotation remains empty.

**Expected behavior:**
The Salesperson field on the quotation should inherit the salesperson assigned to the 
selected customer/contact.

**Cause of the issue:**
When a repair order is created from a helpdesk ticket, default_user_id [1] is passed in the context . 
This value is propagated when creating the repair order [2] . Later, when creating the quotation from 
the repair order [3], the same context is reused.
Because default_user_id is already present in the context, it overrides the precomputation of user_id 
from the customer. As a result, user_id is initialized with an empty value and remains unset.

**Fix:**
This commit ensures that default_user_id is removed from the context before creating the 
sale order. Without a default value for user_id, the field is correctly precomputed from the 
selected customer, and the salesperson is properly assigned.

**Steps to reproduce:**
- Go to CRM app as an internal user (non-admin)
- Click on Generate button
- Can't create leads from business card pictures
- Only setting the user as admin enables it (was working fine in previous versions)

**Issue:**
Dropdown action is restricted to admin only by default using `hasAccess`.
If there is a corresponding model on the `LeadGenerationDropdown` it is later changed according to the current user access rights using `await user.checkAccessRight(model, "create")`.

**Fix:**
Default `hasAccess` to `True` as there is no related model for the lead generation of business cards.
(Note: could also provide the missing model ?)

- Installation should be restricted to the admin.
- Access message should be shown to the user if he doesn't have enough rights to the related model.
- Non-admin users should be able to use the feature if no model is provided and the related app is available.

From the cart, it is possible to increase the amount ordered of a rental product that synchronizes shifts depending on a specific service

Steps to reproduce:
1. Install website_sale_renting_planning module
2. Go to Rental > Products and create a new product "test" with Sales enabled, Product Type "Service", Plan Services enabled as "Developer", in the Sales tab, enable Is Published and in the Rental prices tab, create a pricing for Daily period
3. In the General Information tab, click on the internal link to "Developer"
4. Enable Sync Shifts and Rental Orders
5. Go to the eCommerce website and search for product "test"
6. Add as much product "test" to the cart as possible (the quantity is limited)
7. Open the cart
8. You can increase the amount of the product regardless of its availability

Issue:
We don't check the renting availabilities to limit the maximum quantity of the product

Solution:
Check that the new quantity of the product is available in `_verify_updated_quantity` for the specified dates. We also need to check the availability of the product when we modify the rental dates

**Step To Reproduce:**

1. Configure a POS with German Fiskaly (l10n_de_pos_cert), Restaurant, and Kitchen Display (pos_preparation_display).
2. Create a new order in the POS and add the first product.
3. Observe that the order does not appear on the Kitchen Display.
4. Add a second product to the same order.
5. Observe that the order now appears on the Kitchen Display.

**Issue:**

The first product of a new restaurant order is not synchronised with the Kitchen Display when the German Fiskaly localisation is enabled.

**Reason:**

`syncAllOrders()` only processes orders returned by `getPendingOrder()` and ignores orders explicitly passed through `options.orders`. After the initial Fiskaly synchronisation, the order is serialised and removed from the pending queue. Consequently, the Preparation Display synchronisation receives no orders from `getPendingOrder()`, preventing the order from reaching the backend.

**Solution:**

Update `syncAllOrders()` to prioritize the orders explicitly provided through `options.orders`. When `options.orders` is not available, fall back to the existing behavior by synchronizing the orders from `orderToCreate` and `orderToUpdate`.

### Steps to reproduce:

- In the settings enable: Multi-Steps Routes and rental transfers
- Unarchive the MTO route
- Create a rental product P with a buy route and a set vendor
- Create a rental order for 1 x P and set the the MTO route on the sol
- Confirm the order
#### > The delivery as well as the purchase for 1 unit of P was generated but the return was not.

### Cause of the issue:

The procurement generated to handle both the delivery and the return rental picking are handled by the `_create_procurements`: https://github.com/odoo/enterprise/blob/b0e48baaf99bdc4faefd2ffdd3bd5637fb548593/sale_stock_renting/models/sale_order_line.py#L353-L374 The `route_ids` set and used is the `mto_route` set on the sol: https://github.com/odoo/odoo/blob/0f061503e26ac8c441d62d91947419119e48c47a/addons/sale_stock/models/sale_order_line.py#L415-L422 https://github.com/odoo/odoo/blob/0f061503e26ac8c441d62d91947419119e48c47a/addons/sale_stock/models/sale_order_line.py#L282-L297
However, in the present case, the mto  route does not contain any rule with a relevant `location_src_id` in the rental location so that the return will not be generated.

Currently, an error occurs when a user sets an employee on a payslip.

**Steps to Reproduce:**

 - Install `l10n_hk_hr_payroll` with demo data.
 - Switch to the `Hong Kong` company.
 - Create an `employee` and make sure that the employee's version has no `contract start date`.
 - Go to `Payroll` > `Payslips` > `Payslips`.
 - Create a `payslip` and set that employee.

`TypeError: '<' not supported between instances of 'datetime.date' and 'bool'`

When a user sets an employee on a payslip, the system computes the worked day lines [1]. 
If the salary structure uses worked day lines, it creates the corresponding records [2] and 
calculates out days and out hours based on the contract dates.
During this process, the payslip dates are compared with the version's contract start date. 
If the version does not have a contract start date, it raises an error [3].

This commit ensures that the payslip dates are compared with the version's contract start date, 
and that out days and out hours are calculated only when the contract start date exists. Cases 
where no contract start date is defined are already handled in payslip [4].

**_Steps to reproduce:_**

* Install `l10n_br_avatax` and configure Avalara Brazil.
* Create at least two customer invoices.
* Ensure the fiscal position is set to **Automatic Tax Mapping (Avalara Brazil)**.
* Select the invoices and click **Action → Confirm Entries**.

**_Observed behavior:_**

* A traceback is raised with `ValueError: Expected singleton: account.move(...)` and the invoices cannot be validated.

**_Cause:_**

* During tax extraction, `_extract_tax_values_from_l10n_br_avatax_detail` accesses `self.invoice_filter_type_domain` while `self` may contain multiple `account.move` records.
* Accessing `invoice_filter_type_domain` on a multi-recordset raises an `Expected singleton` error, preventing the validation of multiple invoices.

**_Fix:_**

* Build the returned tax values by iterating over each invoice in the recordset and using the corresponding `invoice_filter_type_domain`.
* This ensures `_extract_tax_values_from_l10n_br_avatax_detail` correctly handles multiple invoices during validation without raising a singleton error.

When using the click & collect option, the available qty for renting was not taking the selected warehouse into account.

Steps to reproduce:
-------------------
* Create 2 different warehouses with 2 different adresses
* Create a product available for renting
* Setup the product to use serial numbers
* Create 2 serial number, 1 in each warehouse
* Activate the click & collect option on the website
* Create a first sale order to collect in warehouse 1
* In the backend, confirm the order and pick it up
* Go back to the website and make a second order for the second warehouse
> Observation: When clicking on the "Add to cart" you get an error
  saying that there is no quantity available

Why the fix:
------------
When computing the `product_rented_quantities` it would look for `sale.order.line` in all the warehouse. So it would find the line from the first order even if it's not linked to the selected warehouse. So we just add a new element to the domain to filter out the incorrect warehouses.

In Italy the periodic VAT return (LIPE) is filed quarterly, so `is_quarter_month` gates the XML export wizard on March, June, September and December. That field only looks at the date, never at the kind of return, so every Italian return locked on a quarter month was treated as a LIPE.

Submitting the withholding tax return therefore opened the LIPE export wizard. Depending on the record the wizard receives, it either crashes while reading the VP lines missing from the withholding report, or silently generates a LIPE file and attaches it to another return.

Add an `is_lipe_return` field telling whether the return actually produces the LIPE.

Steps to reproduce:
- Install `l10n_it_xml_export` and `l10n_it_edi_withholding_reports` on an Italian company with monthly returns
- Open Accounting > Reporting > Tax Return
- Review and submit the withholding returns up to February
- Review then submit the March withholding return --> The LIPE export wizard opens, and the export fails on the withholding report.

**Before this change**
We have the potential to attempt to send a notification email from virtual records created by our `BaseModel.new()` method. This can happen during an `onchange` request, given that we'll be working with a virtual "snapshot" record to recompute potentially changed values for our origin record after a change to one or more values.

This issue manifests when using Studio to attach a many2many field to a form view, where the related model is "Approval Request". If an approval request record in either the "Approved" or "Refused" state is attached to our record via this new Studio field, any `onchange` requests will trigger this bug. This is because we can't send messages on a virtual record.

**After this change**
Prevent the creation and sending of a message if we are computing the request status of a virtual `approval.request()` record. The field `request_status` on this model is computed and stored, but the fact that it is a computed field means that it must be recomputed for a virtual record, even if the origin record already has a stored `request_status`. Thus, we may need to compute a `request_status` value for an ephemeral "snapshot" record.

Though the issue only manifests for the "Approved" and "Refused" states, this PR expands on a test that covers every approval request state.

Purpose:
--------
Instead of handling each AI client tool as a special case when posting a message in the thread, a dedicated registry (ai.client_tools) has been added to make it easy to declare and extend client-side tool handlers: `registry.category("ai.client_tools").add(name, (thread, params) => cb);`

On the Python side, AI tools can now trigger client-side behavior by returning a "client_tool" entry with a name and params, keeping the server interface minimal and consistent.

Updating the thinking text is now done using one of this tool, allowing to update the thinking text more dynamically. For example, the thought will now be updated when the web search tool has been executed.

Also, with this commit, the action domains are not overridden anymore: before, if you asked to open your crm pipeline, it would open it without the default hidden domain (type = 'opportunity'). Now, this domain will be applied, so that the view opened is the same as if the user opened it manually.

#### Async JS tools

Client tools can now pause the agent loop, return a result from the
browser and resume the conversation with this result.

By default, client tools wait for a result from the browser. Tools that
do not need to return a result can set `oneway` to true, allowing the
agent loop to continue without creating a pending tool call (for example
to show a notification).

Tool confirmations and client tool results use the same pending tool
response flow. Confirming a tool re-executes it on the Python side,
while returning a client tool result resumes the loop without
re-executing the tool.

To add a tool that allows the agent to get a result from the browser,
one needs to:
- add an AI tool in the backend that returns a dict with a `client_tool`
  entry: `'client_tool': {'name': name, 'params': {}}`;
- add an AI tool in the frontend with the same name in the
  `ai.client_tools` registry and return the result that needs to be sent
  to the LLM.

For a client tool that does not need to return a result, use the `'oneway'`
option on the `client_tool` entry:
`'client_tool': {'name': name, 'params': {}, 'oneway': True}`

To prevent race conditions that could happen when the user sends a new
message while a client tool is being processed, the send button will now
be disabled when the agent is generating a response.

This commit also removes references to `ai_session_identifier` which was
not used anymore.


Task-6352942

When setting an account to an account.bank.statement there is a step to automatically create a reconciliation rule/model if one does not exist already. To do so, we retrieve 5 account.bank.statement.lines and use them to define the reconciliation model config. A matching is done on the payment_ref of the account.bank.statement.lines by finding the longest common substring in the reference.

### Current Implementation
The current algorithm does so by first generating all the possible substrings for all the payment_ref before doing the intersection between these sets and returning the max if `len(substring) >=10`. This is reasonable when the payment_ref follows either a SEPA communication national standard like the Belgian one or the Creditor Reference standard (ISO 11649). For transactions with large, unstructured communication with more than 100 chars, the method `_get_common_substrings` quickly overfill the memory, sometimes raising a MemoryErorr, and takes a significant amount of time. That's because the nested function `_generate_all_substrings` generates n*(n+1)/2 substrings, with n being the lenght of a payment_ref, called `label` in `generate_all_substrings`.

### Proposed Fix
This commit introduces another algorithm to find the largest common substring. It starts by taking the two smallest labels to find their substrings intersection. We know that for an arbitrary collection of labels, the intersection of their substrings sets A ∩ B ∩...∩ Z is included in the intersection of any two substrings sets. The underlying assumption of the first step is that for an arbitrary collection of labels the intersection of the substrings sets of the two smallest labels will be the smallest intersection of any given pair of substrings sets. This won't hold true everytime and using a metric such as label similarity instead of shortest string might be better. But on average this should be good enough and it's easier to implement + it removes the need of preprocessing the labels to compute the similarity.

The point of the new nested function `common_substrings` is to discard common substrings as we build them. Using the current `generate_all_substsrings` on either the smallest label or both smallest
labels would still generate and store a lot of substrings, especially for large labels. By yielding the common substrings as we find them, the memory footprint is vastly reduced.

Lastly, the next substring in the common_substrings iterable is only checked against the remaining labels if it's longer than the current match. This speeds up the whole process

### speedup

In a customer database with some account.bank.statement.line with payment_ref > 500 chars, setting a specific account (code 4970) on transactions goes from MemoryError to < 1Mb memory consumption.

Because of the memory consumption it was not possible to gather timing value on the current version. 
Testing the new algorithm in a shell and using as labels the 5 longest payment_ref in the customer database
(831, 831, 1117, 1178, 1300 chars), averaging to 2000 chars once normalised, the average time to execute `_get_common_substrings` is 900 ms ± 10.3 ms.

## Problem
When dragging the edge of a scheduled workorder to change the start or end time, _web_gantt_move_candidates would throw a traceback. This is because the web call only supplies the new time chosen by the drag+drop. That is, if date_end was changed, date_start wouldn't be present, so accessing the missing field directly triggers a KeyError. This also revealed a secondary issue involving dependent tasks, where if the parent task is rescheduled with the pills, the child task would fail to find candidate reschedule dates (since its only dependency is being moved), and no boundary date would be supplied when calling _web_gantt_reschedule_compute_dates. This led to another traceback.

## Solution
For the first issue, we will get the start date and end date from the supplied values more safely, using get() to default to the original start/end. For the second issue, if the boundary date isn't found by _web_gantt_get_first_and_last_possible_dates, we fall back to the candidate's existing start or end date.

## Steps to replicate (Runbot saas-19.4)
1. Create a product with a BOM with 2 operations on the same workcenter
2. Create an MO for this product, confirm it, and plan it
3. Head to Manufacturing > Planning > Work Orders / Planning
4. Try to change the end date of the first work order by dragging the edge of the pill

Currently, when a quotation is created from a repair order generated from a helpdesk ticket, 
the salesperson is not set on the quotation even if the customer has a salesperson assigned.

**Steps to Reproduce:**

 - Install `helpdesk_repair`.
 - Go to `Helpdesk` > `Configuration` > `Helpdesk Teams`.
 - Open a team recod and enable `Repairs`.
 - Create a `contact/customer` with a `salesperson` assigned.
 - Go to `Helpdesk`, create a ticket for that `customer`, and select the `helpdesk team` 
   configured above.
 - Click `Repair`, then click `Create Quotation`.
 - Open the quotation and check the `Salesperson` field in the `Other Info` tab.

**Current behavior:**
The Salesperson field on the quotation remains empty.

**Expected behavior:**
The Salesperson field on the quotation should inherit the salesperson assigned to the 
selected customer/contact.

**Cause of the issue:**
When a repair order is created from a helpdesk ticket, default_user_id [1] is passed in the context . 
This value is propagated when creating the repair order [2] . Later, when creating the quotation from 
the repair order [3], the same context is reused.
Because default_user_id is already present in the context, it overrides the precomputation of user_id 
from the customer. As a result, user_id is initialized with an empty value and remains unset.

**Fix:**
This commit ensures that default_user_id is removed from the context before creating the 
sale order. Without a default value for user_id, the field is correctly precomputed from the 
selected customer, and the salesperson is properly assigned.

**Steps to reproduce:**
- Go to CRM app as an internal user (non-admin)
- Click on Generate button
- Can't create leads from business card pictures
- Only setting the user as admin enables it (was working fine in previous versions)

**Issue:**
Dropdown action is restricted to admin only by default using `hasAccess`.
If there is a corresponding model on the `LeadGenerationDropdown` it is later changed according to the current user access rights using `await user.checkAccessRight(model, "create")`.

**Fix:**
Default `hasAccess` to `True` as there is no related model for the lead generation of business cards.
(Note: could also provide the missing model ?)

- Installation should be restricted to the admin.
- Access message should be shown to the user if he doesn't have enough rights to the related model.
- Non-admin users should be able to use the feature if no model is provided and the related app is available.

**Step To Reproduce:**

1. Configure a POS with German Fiskaly (l10n_de_pos_cert), Restaurant, and Kitchen Display (pos_preparation_display).
2. Create a new order in the POS and add the first product.
3. Observe that the order does not appear on the Kitchen Display.
4. Add a second product to the same order.
5. Observe that the order now appears on the Kitchen Display.

**Issue:**

The first product of a new restaurant order is not synchronised with the Kitchen Display when the German Fiskaly localisation is enabled.

**Reason:**

`syncAllOrders()` only processes orders returned by `getPendingOrder()` and ignores orders explicitly passed through `options.orders`. After the initial Fiskaly synchronisation, the order is serialised and removed from the pending queue. Consequently, the Preparation Display synchronisation receives no orders from `getPendingOrder()`, preventing the order from reaching the backend.

**Solution:**

Update `syncAllOrders()` to prioritize the orders explicitly provided through `options.orders`. When `options.orders` is not available, fall back to the existing behavior by synchronizing the orders from `orderToCreate` and `orderToUpdate`.

**Problem:**
On a website with rental planning enabled, a customer can book a planning-backed rental product through eCommerce even when no planning resource is free for the requested window. The cart lets them increase the quantity past the available capacity and proceed all the way through checkout without any availability gate.

**Steps to reproduce:**
1. Install `website_sale_renting_planning`.
2. Create a planning role with `sync_shift_rental` and one resource.
3. Create a service product with `rent_ok=True`, `planning_enabled=True` and the role above.
4. Pre-book the resource for some window via a `planning.slot`.
5. From eCommerce, add the product to the cart for the same window.
6. Proceed to checkout/payment.

**Current behavior:**
The cart is considered ready, no warning is shown, and payment can proceed even though no planning resource is free for the chosen period.

**Expected behavior:**
The cart should be flagged as not ready and pre-payment validation should refuse to confirm until the customer picks a different date or quantity.

**Cause of the issue:**
`sale.order._available_dates_for_renting` in `website_sale_renting` is the documented hook for "stock availability" gating of the cart and pre-payment flow (called from `_is_cart_ready` and from `_check_cart_is_ready_to_be_paid`). `website_sale_stock_renting` overrides it to apply a per-line stock check, but
`website_sale_renting_planning` has no such override, so planning-backed rental services reach payment with no availability gate at all.

**Fix:**
Apply the same gating pattern that `website_sale_stock_renting` already uses: override `_available_dates_for_renting` in `website_sale_renting_planning` so that, for each rental line whose product is a planning-synced rentable service, the cart is only considered valid when at least the requested quantity of planning resources is free during the rental window (mirroring the resource and leave filtering already done by `_planning_slot_vals_list_per_sol` at SO confirmation time). This puts the gate at the same point the stock-renting flow enforces it, keeping the public cart/checkout flow consistent across rentable product types.

**Issue**
When rental transfers are enabled and rental pickups/returns are processed through stock pickings, it may become impossible to perform a subsequent rental return through the rental return wizard.

**Steps to reproduce**
- Activate "Rental Transfers" in the settings
- Create a rental product P, tracked by serial number
- Create two serial numbers for P
- Create and confirm a rental order for 2 units of P
- Validate the pickup transfer
- Partially validate the return transfer without creating a backorder
- Open the rental order and click on "Return" 
-> The return wizard opens without any available serial number and validation fails with a serial number-related error.

**Cause**
When clicking on "Return", if there is no pending pickup/return transfer: https://github.com/odoo/enterprise/blob/d1ba2417affb81c4351ab9f86bc0a6ad5ceb8caf/sale_stock_renting/models/sale_order.py#L62-L68 the rental return wizard is opened directly:
https://github.com/odoo/enterprise/blob/d1ba2417affb81c4351ab9f86bc0a6ad5ceb8caf/sale_renting/models/sale_order.py#L316 No serial number is prefilled in the wizard because `returned_lot_ids` is empty: https://github.com/odoo/enterprise/blob/d1ba2417affb81c4351ab9f86bc0a6ad5ceb8caf/sale_stock_renting/wizard/rental_processing.py#L122-L124 This is because `returnable_lot_ids` is empty as well. `returnable_lot_ids` is computed while generating the wizard lines: https://github.com/odoo/enterprise/blob/d1ba2417affb81c4351ab9f86bc0a6ad5ceb8caf/sale_renting/wizard/rental_processing.py#L38 https://github.com/odoo/enterprise/blob/d1ba2417affb81c4351ab9f86bc0a6ad5ceb8caf/sale_renting/wizard/rental_processing.py#L47-L48 https://github.com/odoo/enterprise/blob/d1ba2417affb81c4351ab9f86bc0a6ad5ceb8caf/sale_stock_renting/wizard/rental_processing.py#L99-L106 and `returnable_lots` is empty because both `pickedup_lots` and `returned_lots` are. Those fields are currently only populated through the rental wizard flow: https://github.com/odoo/enterprise/blob/d1ba2417affb81c4351ab9f86bc0a6ad5ceb8caf/sale_stock_renting/wizard/rental_processing.py#L42-L43 https://github.com/odoo/enterprise/blob/d1ba2417affb81c4351ab9f86bc0a6ad5ceb8caf/sale_stock_renting/wizard/rental_processing.py#L160-L161 https://github.com/odoo/enterprise/blob/d1ba2417affb81c4351ab9f86bc0a6ad5ceb8caf/sale_stock_renting/wizard/rental_processing.py#L166-L167

Since this flow uses stock pickings instead of the rental wizard, those fields are never updated, preventing the wizard from determining any returnable serial number.

### Issue before this commit:
When an invoice's CFDI cancellation request is confirmed (state moves from sent to cancel), reprinting the invoice PDF no longer displays the fiscal information (QR code, digital stamps, fiscal folio/UUID, etc.), even though the signed CFDI attachment is still present on the invoice.

### Steps to reproduce the issue:
1. Download Accounting and l10n_mx
2. Create an invoice and send it to CFDI
3. Select 'Request for cancel'
4. Wait and click retry button in the CFDI tab until the invoice is marked as cancelled
5. Print the invoice again
6. See PDF does not show fiscal information (QR, fiscal folio, etc.)

### Cause of the issue:
https://github.com/odoo/enterprise/blob/f6c94d4ca3ef4211a5ab00bf0b39f6a7675c8f79/l10n_mx_edi/models/account_move.py#L904-L909 Once the CFDI is cancelled, the computed field switches to 'cancel', so the condition fails and the method falls back to the generic account.report_invoice_document template, which has no knowledge of CFDI fiscal fields.

### Reason to introduce the fix:
A cancelled CFDI invoice is still a legally relevant fiscal document in Mexico and must be reprintable with its fiscal data intact (to prove it was issued and later cancelled). The fix extends the condition to also cover the 'cancel' state, ensuring the CFDI-specific report template is used whenever a valid attachment exists, regardless of whether the CFDI is currently signed or cancelled.

**Steps to reproduce:**

- Enable "Move Entire Packages" setting on deliveries
- Make a product A, that has a package P1, on hand qty of 1
- Make product B that don't have a package, but on hand qty of 1
- Make a delivery that has both of those products, requested qty of 1 for both
- Mark it as todo
- Go to the barcode app, select the delivery
- Select the line with product B
- Select the line with product A
--> The line with product B is not unselected

**Why the fix:**

When we have a mix of packaged products and products without a package on the same operation, they are handled separately.
The products without a package are handled in https://github.com/odoo/enterprise/blob/98c79af3fb6cb354f46fd2f58e642a72a9271443/stock_barcode/static/src/models/barcode_model.js#L388-L392 
that calls https://github.com/odoo/enterprise/blob/98c79af3fb6cb354f46fd2f58e642a72a9271443/stock_barcode/static/src/models/barcode_model.js#L1277-L1284 
But as you can see, there are no mention of the selected package line, which is stored in **this.lastScanned.packageId**.

As we do not touch this variable, the selected package line stays selected.

The same is true for the other way around, when we select a package line we call https://github.com/odoo/enterprise/blob/98c79af3fb6cb354f46fd2f58e642a72a9271443/stock_barcode/static/src/models/barcode_model.js#L394-L398 
This function does not care for the **selectedLineVirtualId** which represents the selected line without a package.

To avoid this and make it so that only one line is selected even if they have different package, we now set the corresponding value to false to unselect the other line in all situation.

This is basically how it's done in https://github.com/odoo/enterprise/blob/98c79af3fb6cb354f46fd2f58e642a72a9271443/stock_barcode/static/src/models/barcode_model.js#L1202-L1208 
to unselect every line regardless of packages.

### Issue:
When accessing the Bank Reconciliation view directly via URL or bookmark, auto-matching with reconciliation models may not trigger and the upload button may be visible on synchronized journals

### Cause:
`_action_open_bank_reconciliation_widget` injects two context keys:
- `auto_statement_processing`: triggers auto-reconciliation on statement creation
- `bank_statements_source`: hides the upload button for synchronized journals

When the view is accessed directly, these keys are not present, causing the UI to ignore them

`auto_statement_processing` is now set directly in the user context via `onWillRender`/`onWillDestroy` in `BankRecKanbanController` `bank_statements_source` requires an ORM call to fetch the journal's value and is resolved via `fetchBankStatementsSourceInto` on startup

Notes:
The fix for `bank_statements_source` was added opportunistically while addressing `auto_statement_processing`

Steps to reproduce:
- Install `accountant` with demo data
- Duplicate the Bank Journal and set Bank Feeds to Online Synchronization
- Open the Accounting Dashboard and open the Bank (copy)
- Create a transaction (Label: Test, any amount) and click Add & Close
- In the 3 dots menu, choose Manage Models
- Create a Reconciliation Model (Label contains: Test, Lines: any account, default values)
- Click Automate
- Go back to the Bank Reconciliation page and verify:
 -- The transaction is reconciled automatically
 -- No Upload button is displayed
- Create a new transaction, it should be reconciled automatically
- Copy the URL and open it in a new tab
- Create a new transaction

Before the fix, the transaction is not reconciled and the Upload button is present

…ty of employees

purpose:
1- We should have a consistent way to compute `_gantt_unavailability` of employees in time off and attendance. Currently, some cases have inconsistent behavior such as out of contract days, flexible and fully flexibe employees. 2- In time off calendar view, if the employee does not have a contract at all, the current working schedule will appear in the calendar and it will not be greyed out. This is inconsistent with the behavior of the attendance application.

Fix:
1:
- implemented `_get_employee_unavailable_intervals` in employee model to be used in both time off and attendance.
    - more optimized than the old implementation in time off as it calls `_work_intervals_batch` once per calendar instead of calling it for each contract in `_unavailable_intervals_batch`
    - greys out "out of contract" periods
    - for flexible and fully flexible employees, the whole period is considered available except leave periods
- made `_get_calendar_periods` use version date start instead of contract date start and corrected a bug in tz conversion 2:
- made `_get_unusual_days` return True for all the days outside of contracts for the employee instead of not returning anything for them or getting values from the working schedule of the employee (means that they will be greyed out in the callendar view) and added a test for it

task-id: 5473055

Steps to reproduce:
- set the company currency to XCG
- set the PoS sales journal currency and the PoS pricelist currency to USD
- configure a XCG <-> USD rate
- create a customer without any outstanding balance
- open the PoS, create an order of USD 100 and validate it with the Customer Account (Pay Later) payment method
- open the Customers screen and look at the Total Due of that customer

Issue:
The Total Due shows about USD 55.56, i.e. the amount converted once too many, instead of the expected USD 100.

Cause:
get_total_due() sums two amounts that are not expressed in the same currency before converting them. partner.total_due comes from the accounting entries, it is the sum of account.move.line.amount_residual and is therefore in company currency, while total_settled is the sum of pos.payment.amount of the still open sessions, which is in the currency of the order, so the PoS one. The addition is done first and the result is then converted from the company currency to the PoS one, so the pay later payments end up converted a second time.

Steps to Reproduce:
1. Configure Payment Term (Accounting > Configuration > Payment Terms) containing multiple installments.
2. Create a Customer Invoice with this Payment Term.
3. Post the invoice.
4. Register a payment and fully reconcile one of the installments.
5. Navigate to the customer's Follow-Up Report (Accounting > Reporting > Partner Ledger > Report: Follow-Up Report).
6. Navigate to remaining open installment/account move line for that invoice.
7. Turn On or Off the No Follow-Up toggle for the invoice.

An error occurs when enabling or disabling the No Follow-Up toggle.

Issue:
Enabling or disabling the No Follow-Up toggle on a remaining open installment in the Follow-Up Report raises a server error when the invoice contains multiple installments and one or more installments are already fully reconciled.

Root Cause:
The Follow-Up Report only loads and sends non-fully reconciled account move lines from the JavaScript side through all_line_ids. In action_toggle_no_followup(), when the selected line belongs to an invoice, the code retrieves all receivable/payable lines of the invoice, including fully reconciled installments:

```
move.line_ids.filtered(
    lambda line: line.account_type in ('asset_receivable', 'liability_payable'),
)
```

The method then attempts to map every receivable/payable line to a report line ID using aml_id_to_line_id. Since fully reconciled installments are not present in all_line_ids, they are missing from the mapping dictionary, causing a KeyError when accessing:

`aml_id_to_line_id[line.id]
`

Fix:
Restricted the impacted lines to those present in the report by adding a check that the account move line exists in aml_id_to_line_id before performing the mapping:

```
lambda line: line.account_type in ('asset_receivable', 'liability_payable')
             and line.id in aml_id_to_line_id
```

Steps to reproduce:
1. Install Documents
2. In the Documents list view, select a document to display the inspector.
3. Edit a field such as Owner or Customer which uses a Many2one widget.
4. In the field dropdown, click "Search More..." to open a modal dialog.
5. Click inside the "Search More..." modal (e.g., to sort columns or resize headers).

Issue:
- The modal dialog immediately closes, and the contact cannot be selected.

Root cause:
- When an inspector field is edited, the record row is put into edit mode. While in edit mode, the documents list renderer listens for global clicks. Clicking inside the "Search More..." modal dialog targets elements that have `.o_list_renderer` (since the modal dialog renders a list view). Because the click target is within a list renderer but is not a document row, `DocumentsListRenderer.onGlobalClick` executes and clears the selection of the main list view. Clearing the selection unmounts the edited field in the inspector, thereby destroying the modal dialog stack.

Solution:
- Modify DocumentsListRenderer.onGlobalClick to scope click handling to the current Documents list renderer.
Ignore clicks outside this.root.el, so interactions in nested UI such as Search More... do not clear
the main selection and destroy the inspector field.
