### Description of the issue/feature this PR addresses: 
**Issue**: During KSeF authentication, some foreign qualified certificates causes a crash with error _"Failed to authenticate with XAdES: 400 Client Error: Bad Request for url: https://api.ksef.mf.gov.pl/v2/auth/xades-signature"_ This is due to Odoo not handling different `SubjectIdentifierType`

**Solution**: Implement a try/except block to safely check for the NIP in the certificate's subject string, defaulting the identifier type to `certificateFingerprint` when the NIP is missing or a ValueError is caught.

### Current behavior before PR:
The `SubjectIdentifierType` is hardcoded as `certificateSubject`, and does not handle `certificateFingerprint` at all. This causes there to be an error when trying to authenticate with the KSeF server using XAdES signature.

### Desired behavior after PR is merged:

The sign_authentication_challenge method will now safely evaluate the subject string. It assigns `certificateSubject` only if the NIP is verified to be in the subject string. If the NIP is absent or a ValueError occurs during parsing, the system safely falls back to using `certificateFingerprint`. This prevents tracebacks and ensures the correct XML payload is sent to the KSeF server.

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

The business premises label on Croatian invoices can legitimately contain alphanumeric characters (e.g., "v1"), as noted in the field's tooltip.

However, the regex pattern inside `_get_l10n_hr_fiscalization_number` used to extract the sequence parts strictly expected digits (`\d+`) for the premises label segment. Because of this, if an invoice was generated with an alphanumeric sequence like `INV-2026-0001/v1/1`, the regex failed to match and returned `False`, leading to a traceback when the system attempted to process the fiscalization number.

This commit updates the regex to correctly accept alphanumeric characters for the premises label, ensuring the sequence parses successfully.

opw-6129009

### Steps to reproduce:

- Settings > Users & Companies > Companies > New > set Address country to Croatia
- Select the newly created Croatian company
- Apps > Activate l10n_hr_edi module
- Accounting > Configuration > Accounting > Journals > click Sales journal > change “Business premises label” to “v1”
- Contacts > New > set Address country to Croatia
- Accounting > Customers > Invoices > New > select the newly created contact and choose any product > Confirm

### Current behavior before PR:

Traceback error when attempting to confirm an invoice when both the company and the customer have their country code set to 'HR'. This is because `_get_l10n_hr_fiscalization_number` does not accept alphabet characters in the premises label section of the regex.

### Desired behavior after PR is merged:

- No traceback error when confirming the invoice
- `_get_l10n_hr_fiscalization_number` correctly parses the fiscalization number

Behavior before:
The import flow could crash with an "Expected singleton" error if multiple
journals shared an IBAN. Additionally, the system blindly accepted the
current context ('self') as the target journal, even if its currency or
bank account mismatched the statement, often leading to avoidable
UserErrors.

Behavior after:
The system now validates 'self' against the statement's currency and IBAN
before assignment. If a mismatch is found, it automatically searches for
the correct journal. The search is now restricted by currency and includes
a limit=1 to prevent crashes and ensure accurate selection.

Root Cause:
In _find_additional_data(), 'journal = self' was assigned without validation.
Furthermore, the fallback search lacked a record limit and currency matching
logic, allowing multiple records to be returned when duplicates or
multi-currency setups existed.

Fix:
- Added validation for the initial 'self' candidate (currency and IBAN match).
- Refined the search domain to include currency matching (journal or
  company fallback).
- Added limit=1 to the search to guarantee a singleton recordset.

This commit stabilizes the tour flow by ensuring the sliding panel is
fully closed before proceeding to the next step.

Issue:
The tour steps selects a shape, which triggers [hideSlidingPanel]. That
function focuses a `BuilderButton` after a timeout.

This introduced a race condition: if the timeout executes before the
tour interacts with the `OverlayButtons`, the overlay gets hidden due to
the `focusin` event registered on the builder (outside the iframe) [1],
which ultimately hides the overlay buttons.

The issue made the tour undeterministic following commit [2], which
removed several intermediary steps between the shape selection and the
failing step.

Fix:
Wait for the sliding panel to fully close before continuing the tour
flow.

Currently an error occurs when the user removes the Source Entity Id Type on Super Contributions.

**Steps to Reproduce:**
 - Install `l10n_au_hr_payroll_account` with demo data.
 - Switch to an `Australian` company.
 - Go to `Payroll` > `Reporting` > `Australia` > `Super Contributions`.

After [change] in the selection field behavior, when the user removes the Source Entity Id

When you open a contact, click the Opportunities smart button, then click New and open the Sales Team dropdown, archived sales teams show up in the list. The same thing happens for the user, tags and stage dropdowns. Creating an opportunity from the CRM app does not have this issue.

`res.partner.action_view_opportunity` sets `active_test: False` in the action context so archived opportunities show up in the list view. That context is passed down to the form opened from the action, and to every search the form runs to fill its dropdowns. So the dropdowns also return archived records.

The action's domain already has `('active', 'in', [True, False])`, which is enough to keep archived opportunities in the list on its own (the ORM only adds the "active = True" filter when `active` is not already in the domain). So we can just remove `active_test: False` from the context. This is what 18.0 was doing before https://github.com/odoo/odoo/commit/59feed9f26937ae8e2cab5cd7d2b6743ab6c0717 put the context flag back in.

The override in `website_crm_partner_assign` was setting `active_test: False` back on the action context for the same reason (so its extra search for assigned leads picks up archived ones). The flag is now applied locally on the `crm.lead` handle used for those searches, so archived leads are still found without polluting the action's context.

Steps to reproduce:
1. Archive a Sales Team in CRM > Configuration > Sales Teams
2. Open the Contacts app and pick any contact
3. Click the Opportunities smart button
4. Click "New" and open the Sales Team dropdown

=> Archived teams appear in the dropdown

Steps to reproduce:
===================
1. Configure website with at least 1 language installed different from English. ex: English and French.
2. As anonymous user, change wehbsite language and make a donation via the donation snippet.
3. Check the outgoing confirmation email.

=> Email body is rendered in English.

Cause:
======
The donation confirmation email rendered with `self.partner_id.lang`. For anonymous donors, `partner_id` is the website's shared public user partner, so every anonymous donor received the email in whatever language was set on that partner (or English if unset), regardless of the language they were browsing in.

Solution:
=========
`payment.transaction` already has a `partner_lang` field auto-filled from `partner.lang` at creation.
- override it in the `/donation/transaction` controller with `request.env.lang`
when the public partner is used, capturing the request language at donation time (also works later from `_cron_post_process`, which has no request context);
- render `_send_donation_email` using `self.partner_lang` instead of `self.partner_id.lang`.

The combined query for sale.commission.achievement.report originally performs several bitwise shifts, starting with the max AML ID. This is done to create a composite number ID for the combined IDs.

`MAX(aml.id)::bigint <<20) | max(rules.id)::bigint <<10 | rules.user_id <<10`

This shifts the max aml.id 40 bits to the left.

Example:
Let's say MAX(aml.id) = 1; we will set the other variables to 1, as they often have little impact on the total size of the number.

1 << 20 = 1048576
1048576 | 1 = 1048577
1048577 << 10 = 1099512676352
1099512676352 | 1 = 1099512676353
1099512676353 << 10 = 1152922604119523328

With this format, the highest guaranteed AML ID this query can handle is under 838,861.

The last 10-bit shift is unnecessary and increases the result. If we remove the last shift, the AMD ID this query can handle becomes much higher.

`MAX(aml.id)::bigint <<20) | max(rules.id)::bigint <<10 | rules.user_id`

## Issue
When making a request for quotation for a subcontracted product and returning the delivery "for exchange", the new incoming delivery does not have the correct destination. Instead of having the stock of the user, the destination of the new incoming delivery is the same as its source: the subcontracting location.

<img width="1254" height="257" alt="5479900" src="https://github.com/user-attachments/assets/c7e6d392-8328-4a03-a71e-466e768f448b" />

## Steps to reproduce
1. Install MRP Subcontracting (`mrp_subcontracting`) and Purchase (`purchase`)
2. In Settings, enable *Subcontracting*
3. Create a Product P and a subcontracting BoM with Subcontractor S
4. Create a Request for Quotation
    - Vendor: Subcontractor S
    - Product: Product P (any quantity > 0)
5. Confirm the RFQ, receive the PO, validate the picking
6. On the validated picking, click *Return*, set the quantity of products to return, and click *Return for Exchange*
    - This creates two new pickings, one to return the product(s) we received, and one to receive new products
7. Validate the two new pickings
8. **In Inventory > Reporting > Moves History, the very last `stock.move.line` has the same location in the *From* (`location_id`) and the *To* (`location_dest_id`) columns**

## Cause
The `location_dest_id` of the new `stock.move` is updated in `StockReturnPickingLine._prepare_move_default_values`.

https://github.com/odoo/odoo/blob/fb534f1eadcb8ef74e2ee6fd5b68872dddb978e3/addons/mrp_subcontracting/wizard/stock_picking_return.py#L20-L25

The condition added by https://github.com/odoo/odoo/commit/5404b426aac9 sets the destination of all returned subcontracted moves to the subcontractor location. This is incorrect when using "return for exchange", as in this case, the return move is directed towards the user's stock. In fact, when using "return for exchange", the following pickings are created:

| id | name         | return_id |   |
|:--:|--------------|:---------:|---|
| 1  | WH/IN/00001  |           | Initial RFQ delivery |
| 2  | WH/OUT/00001 |     1     | Return of the initial RFQ delivery |
| 3  | WH/IN/00002  |     2     | New products delivery to replace the initial delivery. The stock.move.line of this stock.picking has a wrong `location_dest_id` |

## Fix
In the context of return for exchanges, the returned item must be directed to the *Subcontracting Location* while the new item must be directed to   the *Stock*. In the `_prepare_move_default_values`, we should only set   the `location_dest_it` to the subcontractor location for outgoing pickings.

**Problem:**
When a project analytic budget is revised, the project update description shows an inflated total budget — the sum of both the original and the revised amounts — instead of reflecting only the active (confirmed) revision.

**Steps to reproduce:**
1. Create a project with an analytic account
2. Create an analytic budget of $10,000 and confirm it
3. Create a revision of that budget for $15,000 and confirm it
4. Create a new project update
5. The update shows "$25,000" as the total budget instead of "$15,000"

**Current behavior:**
The project update displays the sum of all budget revisions ($25,000), regardless of their state.

**Expected behavior:**
Only the active confirmed budget ($15,000) should be used.

**Cause of the issue:**
`_compute_budget` queries all `budget.line` records matching the project's analytic account without filtering by the parent `budget.analytic` state. When a budget is revised, the original transitions to state `revised` while the new one becomes `confirmed`. Because `_compute_budget` has no state filter, it sums both, producing an inflated `total_budget_amount`. This field is then used in the project update template to compute the displayed budget total and percentage. By contrast, `_get_budget_items` — used for the detail rows — already applies `state in ['confirmed', 'done']`, so the two methods were inconsistent.

**Fix:**
Applying the same state filter to `_compute_budget` as already present in `_get_budget_items` ensures both methods draw from the same set of active budgets, keeping the project update totals consistent with the budget detail rows.

# How to reproduce
- Create 2 MO's A & B, both having the same product_id & bom_id
- Split MO A into two MO's A1 & A2
- Merge MO's A1 & B

# The issue
MO A2 no longer has a production group (visible via Studio).
If the user tries to partially produce the MO and create a backorder, a traceback popup appears with :

"ValueError: max() iterable argument is empty"

# Cause
The traceback is triggered because we use the `max()` function on `self.production_group_id.production_ids` when creating the backorder, but `production_ids` is an empty recordset since `production_group_id` is also empty.

The production group is empty because when merging two MO's we delete it without paying attention to other remaining links.

Note : the production groups were introduced by this commit (https://github.com/odoo/odoo/commit/2713876dbc70d3984e584a9037a2206dcda4e84a)

# Proposed solution
When merging, we unlink the original MO's from their production group.
Then, we check every altered production group : if they are not linked to any MO anymore, we delete them.

Overview
------

When searching based on the `Link (short_url)` field in the search bar, in the `link.tracker.click` list view, an error fires up.

How to Reproduce
------

1. Open the Email Marketing app
2. Create a new mailing (or you can use an existing one that has some clicks) and send it
3. Make a click in the email from the recipient's side
4. Open the link tracker `click` related to that mailing (select the mailing → `Link Trackers` stat button → click on a link → `Clicks` stat button)
5. Make a search based on the Link (short_url) field

Expected Behavior
------

Return the list of links that matches the entered search query.

Current Behavior
------

Odoo Server Error.

Cause & Solution
------

The cause of this error is that the `shor_url` field is a computed, non-stored, field, and hence, we cannot directly make a search on it. So, either we make the `short_url` a stored field, which is not so efficient, or we create our own custom `_search_..` method.

| 2  | WH/OUT/00001 |     1     | Return of the initial RFQ delivery |
| 3  | WH/IN/00002  |     2     | New products delivery to replace the initial delivery. The stock.move.line of this stock.picking has a wrong `location_dest_id` |

## Fix
In the context of return for exchanges, the returned item must be directed to the *Subcontracting Location* while the new item must be directed to   the *Stock*. In the `_prepare_move_default_values`, we should only set   the `location_dest_it` to the subcontractor location for outgoing pickings.

The combined query for sale.commission.achievement.report originally performs several bitwise shifts, starting with the max AML ID. This is done to create a composite number ID for the combined IDs.

`MAX(aml.id)::bigint <<20) | max(rules.id)::bigint <<10 | rules.user_id <<10`

This shifts the max aml.id 40 bits to the left.

Example:
Let's say MAX(aml.id) = 1; we will set the other variables to 1, as they often have little impact on the total size of the number.

1 << 20 = 1048576
1048576 | 1 = 1048577
1048577 << 10 = 1099512676352
1099512676352 | 1 = 1099512676353
1099512676353 << 10 = 1152922604119523328

With this format, the highest guaranteed AML ID this query can handle is under 838,861.

The last 10-bit shift is unnecessary and increases the result. If we remove the last shift, the AMD ID this query can handle becomes much higher.

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

The business premises label on Croatian invoices can legitimately contain alphanumeric characters (e.g., "v1"), as noted in the field's tooltip.

However, the regex pattern inside `_get_l10n_hr_fiscalization_number` used to extract the sequence parts strictly expected digits (`\d+`) for the premises label segment. Because of this, if an invoice was generated with an alphanumeric sequence like `INV-2026-0001/v1/1`, the regex failed to match and returned `False`, leading to a traceback when the system attempted to process the fiscalization number.

This commit updates the regex to correctly accept alphanumeric characters for the premises label, ensuring the sequence parses successfully.

opw-6129009

### Steps to reproduce:

- Settings > Users & Companies > Companies > New > set Address country to Croatia
- Select the newly created Croatian company
- Apps > Activate l10n_hr_edi module
- Accounting > Configuration > Accounting > Journals > click Sales journal > change “Business premises label” to “v1”
- Contacts > New > set Address country to Croatia
- Accounting > Customers > Invoices > New > select the newly created contact and choose any product > Confirm

### Current behavior before PR:

Traceback error when attempting to confirm an invoice when both the company and the customer have their country code set to 'HR'. This is because `_get_l10n_hr_fiscalization_number` does not accept alphabet characters in the premises label section of the regex.

### Desired behavior after PR is merged:

- No traceback error when confirming the invoice
- `_get_l10n_hr_fiscalization_number` correctly parses the fiscalization number

Currently an error occurs when the user removes the Source Entity Id Type on Super Contributions.

**Steps to Reproduce:**
 - Install `l10n_au_hr_payroll_account` with demo data.
 - Switch to an `Australian` company.
 - Go to `Payroll` > `Reporting` > `Australia` > `Super Contributions`.
 - Open an existing record or create a new one.
 - Remove the `Source Entity Id Type` value and click anywhere.

`ValueError: Compute method failed to assign l10n_au.super.stream(<NewId origin=1>,).source_entity_id`

After [change] in the selection field behavior, when the user removes the Source Entity Id 
Type, the compute method is triggered to compute the Source Entity ID. However, the 
condition in the compute method is not match, so no value is assigned. As a result, 
the method fails and raises an error.

This commit ensures that if the condition is not match, the Source Entity ID is explicitly

When you open a contact, click the Opportunities smart button, then click New and open the Sales Team dropdown, archived sales teams show up in the list. The same thing happens for the user, tags and stage dropdowns. Creating an opportunity from the CRM app does not have this issue.

`res.partner.action_view_opportunity` sets `active_test: False` in the action context so archived opportunities show up in the list view. That context is passed down to the form opened from the action, and to every search the form runs to fill its dropdowns. So the dropdowns also return archived records.

The action's domain already has `('active', 'in', [True, False])`, which is enough to keep archived opportunities in the list on its own (the ORM only adds the "active = True" filter when `active` is not already in the domain). So we can just remove `active_test: False` from the context. This is what 18.0 was doing before https://github.com/odoo/odoo/commit/59feed9f26937ae8e2cab5cd7d2b6743ab6c0717 put the context flag back in.

The override in `website_crm_partner_assign` was setting `active_test: False` back on the action context for the same reason (so its extra search for assigned leads picks up archived ones). The flag is now applied locally on the `crm.lead` handle used for those searches, so archived leads are still found without polluting the action's context.

Steps to reproduce:
1. Archive a Sales Team in CRM > Configuration > Sales Teams
2. Open the Contacts app and pick any contact
3. Click the Opportunities smart button
4. Click "New" and open the Sales Team dropdown

=> Archived teams appear in the dropdown

Currently, an error occurs when a user selects a shift template on a planning slot.

**Steps to Reproduce:**

 - Install the `Planning` module with demo data.
 - Create a `Resource Time Off` record with `start` and `end date` separated by more than 
  `1400 days (around 3.9 years)`, and Set the Working Hours field to Standard 40 hours/week.
 - Go to `Planning` > `Configuration` > `Shift Templates`, open an `existing record` or create 
   a `new one`, and set the `Working Days` to more than 1 day.
 - Create a new `planning slot`, Assign the resource `Abigail Peterson`, and select the above 
   `shift template`.

`AttributeError: 'bool' object has no attribute 'replace'`

This error occurs because when the user sets the shift template, the compute method runs to 
calculate the start and end datetimes [1]. It computes the end datetime by adding the template 
duration in working days from the given start datetime using the resource working calendar within 
a searchable range of around 1400 days [2]. During this computation, leaves and non-working days 
are skipped [3]. If no valid working interval is found within the searchable range, then it returns 
False [4], which raises the error [5].

This commit ensures that if plan_days returns False, the computation falls back to the previously 
calculated end date.

When generating a VAT return with an unclaimed tax amount carried to the
next month, the carryover reimbursement move amounts are computed with
an incorrect ratio.

Steps to reproduce:
- Create and post a bill in May containing a VAT amount.
- Create and post a bill in June containing a VAT amount.
- Create a VAT return for May to carry over the VAT amount to the next
  month.
- Create a VAT return for June, requesting the full VAT amount to be
  reimbursed.
- Validate and send the June VAT return.
- Check the generated reimbursement move

Issue: Line values does not correspond to anything real/tangible.  It
occurs because when computing the ratio for the move we check the last
tax report entry, where we find the amount of tax from the past months
and a line balancing the last month that should not be taken into
account.  The "Balance tax current account (receivable)" line from the
tax closing entry is mistakenly picked up as a tax carried forward line,
throwing off the amounts.

## Short functional explanation of the error
When checking the dashboard on a project we created with a yearly subscription, the values shown are incorrect.

## Reproduction Steps
1. Create a new product. Check the Subscription field and set the Product type as Service. On the Create on Order field, set Project & Task. Then, in the Recurring Price tab, add a Monthly plan with price 50 and yearly plan with price 40.
2. Create a new Quotation. Set a customer and add the product you just created in an Order line. Set the Quantity to 100 and set the recurring plan as Yearly. You'll see the amount be at 4000, and the total amount at 4600 with taxes. Click on Confirm.
3. Create an invoice and confirm it.
4. Click on the Project smart button. Then, on the top right, click on the view menu > Top Menu. Select Dashboard and click on it.

### Expected behavior
On the dashboard, we should see the Revenues under Profitability at 4000. To invoice should be left at 0 and Invoiced should be at
4000. Expected should be at 4000.

### Unexpected behavior
On the dashboard, To Invoice is at 333, and Expected is at 4333. This corresponds to our invoice + 4000/12 -> monthly recurring plan, with the price of the yearly plan!

## Origin of the issue
We always add the `recurring_monthly` value when showing the profitability, no matter the recurring plan:
https://github.com/odoo/enterprise/blob/cdc0d5d57f6b27a6bb5e451d48bdbef4e3dde5cb/project_sale_subscription/models/project_project.py#L86
We should only add the `recurring_monthly` value for as many monthly
subscriptions we have, not for *all* the subscriptions.

Steps to reproduce:
===================
1. Go to the shop page and use the rental date picker to select a start and end date with hours.
2. Find a rental product configured with "Days" pricing.
3. Add to card directly from the product card
4. Add a rental product from product image that has date type value date
5. Go to that product details page.
6. Click add to cart

-> Invalid operation, You cannot mix different rental periods...

Cause:
======
When adding a product from the shop list view, the system uses the default start/end dates (from the rental period) exactly as first added.

However, the "Add to Cart" logic on the product details page attempts to adapt the selected dates to the product's specific rental unit (e.g., normalizing the time component for 'Day' pricing).

This re-calculation creates a timestamp mismatch between the item already in the cart (from the shop view) and the new item being added (from the details page).

Solution:
=========
The add-to-cart flow has been updated to correctly utilize the default duration values (the globally selected dates) if they exist.

**Problem:**
When a project analytic budget is revised, the project update description shows an inflated total budget — the sum of both the original and the revised amounts — instead of reflecting only the active (confirmed) revision.

**Steps to reproduce:**
1. Create a project with an analytic account
2. Create an analytic budget of $10,000 and confirm it
3. Create a revision of that budget for $15,000 and confirm it
4. Create a new project update
5. The update shows "$25,000" as the total budget instead of "$15,000"

**Current behavior:**
The project update displays the sum of all budget revisions ($25,000), regardless of their state.

**Expected behavior:**
Only the active confirmed budget ($15,000) should be used.

**Cause of the issue:**
`_compute_budget` queries all `budget.line` records matching the project's analytic account without filtering by the parent `budget.analytic` state. When a budget is revised, the original transitions to state `revised` while the new one becomes `confirmed`. Because `_compute_budget` has no state filter, it sums both, producing an inflated `total_budget_amount`. This field is then used in the project update template to compute the displayed budget total and percentage. By contrast, `_get_budget_items` — used for the detail rows — already applies `state in ['confirmed', 'done']`, so the two methods were inconsistent.

**Fix:**
Applying the same state filter to `_compute_budget` as already present in `_get_budget_items` ensures both methods draw from the same set of active budgets, keeping the project update totals consistent with the budget detail rows.

When selling event tickets in POS while offline, the order could be synced later but without creating event registrations (tickets) after a page reload.

Steps to reproduce:
-------------------
* Open a POS session with `pos_event`
* Sell an event ticket
* Switch to offline mode
* Validate payment while offline (order becomes paid but unsynced)
* Reload/close and reopen POS, then reconnect
* Let the order sync

> Observation:
The `pos.order` is created on the backend, but `event.registration` and `event.registration.answer` are missing so tickets are not generated.

Why the fix:
------------
`pos_event` used `order.finalized` as IndexedDB cleanup condition for `event.registration` and `event.registration.answer`. For paid-but-unsynced orders, `finalized` is already true, so those records can be removed from IndexedDB too early. After reload, the order is restored/synced but without its event registration payload.

Implementation:
---------------
Use `order.canBeRemovedFromIndexedDB` instead of `order.finalized` for `event.registration` and `event.registration.answer` retention rules, so records are kept locally until the order is truly synced (server id assigned) or canceled.

Test Note:
---------------
Use case is hard to simulate exactly.
Add a basic unit test to assert both registration models are kept for paid unsynced orders and only removable once synced.

Commit 28b840b introduced logic to include `freight_costs` in the customs document generated bySendcloud. It introduced 2 new issues as a result:

1. When creating backorders, the `freight_costs` are not divided but instead propagated to all of the pickings.
2. When there is no SO, we were taking the total value of all delivered goods, which doesn't make much sense considering the `freight_costs` field should be the cost of the delivery itself.

Solution
-----
For the first problem, there are a couple things to keep in mind:
- the total `freight_costs` declared to the customs entity should be the amount invoiced to the customer
- products can be added and removed from the picking after the SO has been confirmed
- actual delivery cost can change between invoice date and actual delivery date
- picking can be split into multiple packages at the user's discretion

Considering all of the above, we will simply forward the invoiced amount with the first confirmed picking and none of the backorders.

**Problem**
When opening a timesheet record from the *My Timesheets* grid view (via the magnifier icon that appears on cell hover) and refreshing the page, the wrong form view is loaded: the generic "Analytic Items" form on `account.analytic.line` instead of the timesheet-specific form.

**Steps to reproduce**
1. Go to *Timesheets* → *My Timesheets* → switch to **Grid** view.
2. Hover a cell with a timesheet entry and click the magnifier (search) icon.
3. The list opens; click a record to open its form view.
4. Observe the URL: `/odoo/timesheets/<id>`.
5. Refresh the page (F5).

**Expected**
The same timesheet form view is shown after refresh.

**Actual**
The "Analytic Items" form view (`analytic.view_account_analytic_line_form`) is shown instead, exposing the wrong layout/fields.

**Cause**
The grid renderer's `openRecords` builds an inline `ir.actions.act_window` with no `path` and no `id`. When the page is refreshed, the action service reconstructs the action from the URL state alone — model + resId — and resolves the form view by priority. Two priority-1 form views exist on `account.analytic.line` (`analytic.view_account_analytic_line_form` and `hr_timesheet.hr_timesheet_line_form`); the lower-id one wins, which is the analytic one.

**Fix**
Override `openRecords` in `TimesheetGridRenderer` to carry the current action's `path` (or `id`, for non-pathed database actions) onto the inline action. The URL then stays anchored to the original act_window (e.g. `/odoo/timesheets/<id>`), and on refresh the action service rebuilds it with the correct views, including the timesheet-specific form.

[FIX] hr_attendance_gantt: fix gantt view with public holidays

Bug reproduction:
    1 - Select flex schedule employee (or change its schedule to 40h flex one) and make its contract before 01/01/2026
    2 - Create a new public holiday on 01/01/2026 (from 00.00 to 23.59 or 23.55 (depends on version, it does not matter))
    3 - in attendance app the cell from 00.00 to 01.00 seems white for that day and for selected employee (this cell seems like not holiday and employee can work)

Bug cause:
    1 - After a long traceback, _gantt_unavailability in hr_attendance_gantt/HrAttendance, if an employee is flexible then unavailable_intervals is calculated with the Brussel time zone
    2 - All other unavailable intervals are converted to the UTC in the function of _gantt_unavailability except in the final lines of the function.
    3 - When the employee is flexible and since the conversion is not done in the final lines, it remains 1 hour more (UTC+1), it is from 1 am to 1 am of next day instead of 0 am to 23.59.

Bug solution:
    1 - I converted the timezone to UTC to solve the problem.

### Description of the issue/feature this PR addresses: 
**Issue**: During KSeF authentication, some foreign qualified certificates causes a crash with error _"Failed to authenticate with XAdES: 400 Client Error: Bad Request for url: https://api.ksef.mf.gov.pl/v2/auth/xades-signature"_ This is due to Odoo not handling different `SubjectIdentifierType`

**Solution**: Implement a try/except block to safely check for the NIP in the certificate's subject string, defaulting the identifier type to `certificateFingerprint` when the NIP is missing or a ValueError is caught.

### Current behavior before PR:
The `SubjectIdentifierType` is hardcoded as `certificateSubject`, and does not handle `certificateFingerprint` at all. This causes there to be an error when trying to authenticate with the KSeF server using XAdES signature.

### Desired behavior after PR is merged:

The sign_authentication_challenge method will now safely evaluate the subject string. It assigns `certificateSubject` only if the NIP is verified to be in the subject string. If the NIP is absent or a ValueError occurs during parsing, the system safely falls back to using `certificateFingerprint`. This prevents tracebacks and ensures the correct XML payload is sent to the KSeF server.

Before this commit:
1. Create a POS order with no discount and a quantity that does not divide evenly into the unit price (e.g. price=10.0, qty=3)
2. Send the order to Jofotara

Jofotara rejects the invoice because the AllowanceCharge/Amount on the invoice line is a small negative value like -0.000000001 with the error `"EINV_MESSAGE":"discount cannot be negative"`

This happens because _add_document_line_gross_subtotal_and_discount_vals computes the discount as: gross_subtotal - total_excluded_currency

where gross_subtotal goes through two independent rounding steps (round unit price, then round unit_price * qty). When the quantity is indivisible, the reconstituted gross_subtotal can land just below total_excluded_currency by a floating-point epsilon, producing a tiny negative discount. The same subtraction also produces a legitimate negative value for refund lines (negative quantity), which was already handled by abs() in _add_pos_order_discount_vals for the document-level total but was left unguarded at the per-line level.

After this commit:

Apply abs() to vals[f'discount_amount{currency_suffix}'] in _add_pos_order_line_allowance_charge_nodes so that discount_amount_currency is always non-negative.

Steps to reproduce
1. Install hr_holidays and hr_contract.
2. Take a demo employee currently on a validated time off covering now.
3. Set the employee's running contract Working Schedule to empty (fully flexible).
4. Run the "HR Contract: update state" cron (or otherwise leave the contract in state open / close, or draft + kanban Ready).
5. Open the Employees app or any view rendering that employee's chatter / follower panel.

Issue
A traceback "Expected singleton: resource.calendar()" is raised. If the employee's chatter is open, the failing compute is re-fired on every store refresh and the UI becomes unusable.

For fully flexible contracts, hr.contract has no resource_calendar_id, so _get_calendar_periods appends period tuples with an empty calendar recordset (https://github.com/odoo/odoo/blob/c6d9fa5873eb759846e9be5b66eedb8b00c5ac11/addons/hr_contract/models/hr_employee.py#L184). _get_first_working_interval then forwarded that empty recordset to _work_intervals_batch, which calls ensure_one() and crashes.

This regressed when _compute_leave_status was switched from a single calendar lookup to per-period iteration in
https://github.com/odoo/odoo/commit/bf73b63eec56a822edec2d9ecfeb231a0fbfbbe8 which did not consider that a period in the chain can come from a contract with no calendar.

Solution
Fall back to the company's calendar when the period's calendar is empty, matching the guard already present from saas-18.4 onwards in https://github.com/odoo/odoo/commit/21f18b1a6fdbf1a01c3dda83acfa66addd01a759.
