### Steps to reproduce the issue:
1. Download Accounting
2. Go to Journal entries and create a new one
3. Click Toggle Studio button and go to the view to add the tax_base_amount field to the list of existing fields
4. Add 2 lines (example):
	1. account Product Sales with 1000 dollars credit and 15% tax under Tax column
	2. account Bank with 1000 dollars debit
5. Go to Dashboard > Bank > Click the 3 dots of one random bank matching line and click on Manage Models
6. Go to bank fees and add the 15% tax
7. Go back to bank reconciliation and create a new one of 2000 dollars with label bank fees (it will associate the tax automatically)
8. Go back to Journal Entries, group by Journal and search for the transaction of 2000 sollars for account Bank
9. Problem: see that the Base Amount for the 15% bank fees lines (251000 Tax Received account) is 0. Clicking on Reset to draft button the base amount column is automatically updated but this should happen automatically

### Cause of the issue:
This occurs because the _lines_prepare_tax_line method in account.bank.statement.line fails to map this field in its return dictionary.

### Reason to introduce the fix:
Currently, when applying a reconciliation model with taxes the generated tax lines incorrectly record a tax_base_amount of $0.00. Instead, it should be displayed and calculated.

When an employee's Income Stream Type is changed after a payslip has been created,
computing the sheet for payslip will raise a traceback.

Steps to reproduce the  error:
- Install ``l10n_au_hr_payroll_account`` module with demo data
- Switch to ``My Australian Company`` company
- Create a new payslip for ``Dennis Cactus`` Employee > Save
- Go to Employees > Open the ``Dennis Cactus`` employee >
  In Payroll tab, Income Stream Type: Other specified payments > Save
- Go back to payslip > click the compute sheet button

Traceback:
```py
KeyError: 'OSP'
```

https://github.com/odoo/enterprise/blob/13e64e0cb7f566cbbb46109fe1c218eb7a14eead/l10n_au_hr_payroll/models/hr_payslip.py#L175-L178
The ``l10n_au_income_stream_type`` field on the payslip is a computed field that only depends on ``employee_id``.
As a result, changing the employee's Income Stream Type does not trigger a recomputation of the corresponding field on existing payslip.
So, when the ``payslip_ytd_totals`` field is computed, it uses the old value of ``l10n_au_income_stream_type`` field at [1], The resulting ``payslip_ytd_totals`` is then used to build the ``totals`` dictionary, and eventually, when the employee's current ``income_stream_type`` is used to access
``totals``, the mismatch key leads to the above traceback. https://github.com/odoo/enterprise/blob/13e64e0cb7f566cbbb46109fe1c218eb7a14eead/l10n_au_hr_payroll_account/models/hr_payslip.py#L75-L88

solution:

I added ``l10n_au_income_stream_type`` to ``add_to_compute()`` in ``compute_sheet()``.
This ensures that stale values of ``l10n_au_income_stream_type`` on
existing payslips are recomputed when the payslip sheet is computed.

Steps to reproduce:
----------------------------------------
1. Install `industry_fsm_sale` and `base_automation` modules
2. Create a product with:
    * Type: Service
    * Create on order: Task
    * Project: Field Service
3. Create an automation rule with:
    * Model: Sales order
    * Trigger: Incoming message
4. Create and confirm a sale order with this product
5. Add another product to the SO via the catalog view:
    * Change the quantity to 2 or more

Observation:
----------------------------------------
Traceback occurs:
```
  File '/home/odoo/src/odoo/addons/base_automation/models/base_automation.py', line 871, in _message_post
    message_sudo = message.sudo().with_context(active_test=False)
AttributeError: 'bool' object has no attribute 'sudo'
```

Root Cause:
----------------------------------------
* Catalog qty change calls `set_fsm_quantity()` method
* Setting `fsm_quantity` triggers its inverse `_inverse_fsm_quantity()`, which writes the new qty to the SOL, but passes `fsm_no_message_post=True` in context to suppress chatter noise
https://github.com/odoo/enterprise/blob/ac5d670832a5e0db714c0bd056e1406b50bb4c17/industry_fsm_sale/models/product_product.py#L72-L83
* `sale.order.line.write()` detects a qty change on a confirmed order and calls `_update_line_quantity()`, which posts a message on the parent sale order
* FSM's `message_post` override sees the context flag and returns `False`
* When `base_automation` has an `on_message_received` rule on `sale.order`, it wraps `message_post` at registry load time. That wrapper calls `sudo()` on whatever `message_post` returns, Which was `False`

Solution:
----------------------------------------
Return `self.env['mail.message']` (empty recordset) instead of False, it's still falsy, but it's a proper ORM object that `sudo()` can be called on

- Create a Belgian company
- Setup DHL
	- DHL Product D - Express Worldwide
	- Dutiable Material enabled
- Create an amrican customer
- Deliver a product to the american customer

The problem is that `next_by_code` uses the company found in the env, whereas the sequence's company is the main one, so it is not found when doing

The Download PDF option of an article prints the page with the browser. On screen, the article body is inside .o_scroll_view_lg, which scrolls when the content is longer than the screen:

https://github.com/odoo/enterprise/blob/79f8defa04476e1b939dc8bb5449a775137aed62/knowledge/static/src/scss/knowledge_views.scss#L170-L177

The print stylesheet used to force overflow: visible on every div, so this container did not scroll when printing. It also hid every child of the body except the action manager, so the navbar and open dropdowns were left out of the print. Commit https://github.com/odoo/enterprise/commit/69612c80ea0aec5ccf2c2857449da03e61273457 rewrote knowledge_print.scss to scope its rules to the Knowledge view and removed both rules. The scroll container now keeps its fixed height and its scrollbar when printing, so the scrollbar is drawn in the print preview and on every page of the PDF. The dropdown opened to reach Download PDF is printed on top of the article when it overlaps the page area, which happens when the browser is zoomed in.

Add overflow: visible to the print rule of knowledge_print.scss that already targets .o_scroll_view and .o_scroll_view_lg with position: static. That rule exists to undo the screen positioning of the scroll containers when printing, so the overflow reset belongs there. Its selector is also more specific than the screen one, so the value applies without !important, like position: static already does. Restore the rule that hides the body children other than the action manager, scoped to the Knowledge view like the rest of the file since the print stylesheet is now loaded on every page.

Before:
<img width="497" height="703" alt="image" src="https://github.com/user-attachments/assets/44aa3366-3fc8-4382-8aa2-84625fa4b6d8" />

After:

Steps to reproduce:
1. Open the Knowledge app and create an article
2. Paste enough text in the article to fill more than one PDF page
3. Zoom the browser to 200%
4. Click the three dots in the top right corner, then Download PDF
5. Check the print preview or the saved PDF

=> A scrollbar is drawn on the right edge of every page and the dropdown menu is printed on top of the article

opw-6279174

Forward-Port-Of: odoo/enterprise#120249

Steps to reproduce:
- Create one user linked to two companies.
- Create one employee per company for that user.
- Select one company and approve a time off for the employee.
- Open Tasks > Gantt and create a task during the approved time-off period the warning is shown and the Gantt cell is grayed out.
- Select both companies and create a task during the same time-off period in Tasks > Gantt.

Issue:
When multiple companies are selected, the time-off warning is still displayed but the corresponding Gantt cells are no longer grayed out, leading to an inconsistency between the warning logic and the Gantt rendering.

Cause:
In multi-company setups, a user can be linked to multiple resources. The Gantt unavailability logic assumed a one-to-one relationship between user and resource causing unavailability intervals from some resources to be overwritten.

Solution:
Aggregate unavailability intervals from all resources linked to the same user, limited to the selected companies, and merge them with the company calendar unavailability to ensure consistent Gantt gray rendering.

**Steps to Reproduce:**
- Create an employee with at least one validated work entry.
- Modify the employee's resource_calendar_id.
- The schedule change triggers work entry recomputation.
- During regeneration, the employee is excluded because of the validated work entry.
- No valid employees remain for regeneration.

**Issue:**
- Employees with validated work entries are excluded from: `valid_employees = self.employee_ids - self.validated_work_entry_employee_ids`
- When all employees are excluded, `valid_employees` becomes empty.
- The flow still calls: `valid_employees.generate_work_entries(date_from, date_to, True)`
- An empty employee recordset causes `generate_work_entries()` to follow the global generation path and fetch all employee versions in the requested period. `_get_all_versions_with_contract_overlap_with_period(date_start, date_stop)`
- This can trigger unintended global work entry regeneration and cause severe performance issues on large databases.

**Root Cause:**
- The regeneration flow does not stop when no valid employees remain after excluding employees having validated work entries.

- As a result, generate_work_entries() is called with an empty employee recordset, which falls back to the global generation path.

**Solution:**
- Stop the regeneration flow when the valid employee recordset is empty Because the employee already has a valid work entry, there is no need to regenerate.

**Result:**
- Prevents unintended generation on all employee versions.
- Avoids unnecessary performance degradation on large databases.
