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

- Install `sale_timesheet_enterprise`.
- Go to **Tasks → All Tasks**.
- Switch to the **Gantt** view.
- Group by **Sale Order Item** (`sale_line_id`).

### Issue

A traceback is raised when loading the Gantt view with group by `sale_line_id`:

```text
ValueError: Invalid field 'planned_hours' on model 'project.task' for 'planned_hours:sum'
```

### Root cause

The Gantt progress bar computation for the `sale_line_id` grouping performs a `_read_group()` aggregation on the `planned_hours` field of `project.task`.

However, `planned_hours` was renamed to `allocated_hours` during the saas-16.5 migration, so the former field no longer exists on `project.task`. As a result, the aggregation raises a `ValueError`.

Migration reference:
https://github.com/odoo/upgrade/blob/e638c6ce00d9d8936d034ad7130fef51565b9195/migrations/project/saas~16.5.1.2/pre-migrate.py#L10

Issued PR: https://github.com/odoo/enterprise/pull/49685

### Fix

Use `allocated_hours`, the renamed equivalent of `planned_hours`, when computing the Gantt progress bar. This restores the Gantt view when grouping tasks by **Sale Order Item** and prevents the traceback.

Steps to Reproduce
---
- Create two different working schedules with different public holidays
- Assign employees to specific working schedules
- Set company default working schedule to a different schedule
- Login as employee with specific working schedule
- Navigate to Timesheets app -> My Timesheets
- Observe public holidays and personal time-off displayed in the timesheet grid

Issue
---
- The timesheet grid displays unavailable dates (public holidays, weekends) from the company's default working schedule instead of the employee's assigned working schedule.
- Personal time-off requests are not reflected as unavailable dates in the timesheet grid.

Current Behaviour
---
- Public holidays shown are always from the company's default working schedule, ignoring employee-specific working schedule assignments.
- Employee's approved time-off requests don't appear as unavailable in the timesheet.

Expected Behaviour
---
- Public holidays should display based on the employee's assigned working schedule, with company schedule as fallback only when no specific schedule is assigned.
- Employee's personal time-off requests should appear as unavailable dates.
- This should align with Time Off app behavior.

Fix
---
- Included employee-specific work interval calculation with personal time-off requests.
- Added support for contract-based calendar changes and calendar validity periods.
- Implemented proper fallback when valid intervals are not found.

When Google sends a recurrence with UNTIL in UTC (UNTIL=...Z), users in timezones behind UTC can get one extra occurrence on the boundary day. Google's UNTIL represents the last allowed start in UTC, but that UTC date fell into the previous local day. Because Odoo was comparing event start times as naive local datetimes against a cutoff derived from the wrong date, the boundary occurrence passed the check and was created.

Steps to reproduce:
1. Set the user's timezone to a UTC-negative offset (e.g. America/Argentina/Buenos_Aires, UTC-3).
2. In Google Calendar, create a weekly recurring event (e.g. every Thursday at 12:00 local).
3. Edit the series with "This and following events" so the old series ends with UNTIL set to 02:59:59 UTC of the next day (= 23:59:59 local of the last valid occurrence day).
4. Sync with Odoo -> an extra event is created on the day after the last valid Thursday, which does not exist in Google Calendar.

`_l10n_tr_nilvera_add_pdf_to_invoice` writes the response from `client.request('GET', '.../pdf')` directly into `ir.attachment.raw`. The Nilvera client sets `Accept: application/json` on the session and calls `response.json()` by default, so the returned value is a Python `str` holding the base64-encoded PDF body, not raw binary bytes.

The previous code wrote to the base64-aware `datas` field, which auto-decoded its input. An earlier fix switched to `raw` to work around a `binascii.Error` from Python 3.14's stricter base64 validation in the `datas` auto-decode path. That switch silently changed what ends up on disk (`datas` decodes its input, `raw` does not)

Storing that string in the binary `raw` field encodes it as UTF-8, so the file on disk ends up as the literal ASCII of the base64 text. The attachment is served as `application/pdf` but the browser receives base64 ASCII and cannot preview or download the PDF.

Call `b64decode(response)` before storing so the attachment contains the actual PDF bytes.

Steps to reproduce:
1. Install l10n_be and switch to BE company
2. Upload the XML document (found in ticket chatter) into the Accounting application as a Credit Note.

Issue:
 - The line is imported as a negative value which is corrected with a rounding line.
 - The 6% tax rate is applied to the negative invoice line, resulting in a negative tax amount being deducted from the total (e.g., 449.32 + (-26.96) = 422.36) instead of being added (449.32 + 26.96 = 476.28)

Expected behavior:
price_unit, quantity and the related tax amounts should all be
positive, matching a normal in_refund/out_refund line.

Why this happens:
 - In `_import_ubl_invoice_line_add_price_unit_quantity_discount`,
  `BaseQuantity` was multiplied by file_document_sign, unlike
  `PriceAmount` from the same node which is left untouched.
  This flips price_quantity to -1, which later flips price_unit to
  negative when `price_unit = price_subtotal / price_quantity`.

**Steps to reproduce:**
- Install Accounting and l10n_ar_withholding
- Switch to an Argentinian company (e.g. (AR) Responsable Inscripto)

- Create a 0% Payment Withholding tax:
  * Tax Type: Customer Payment Withholding
  * Amount: 0.00 %
  * Add an account for the tax distribution lines

- Create an invoice with a tax
- Confirm the invoice
- Pay the invoice:
  * Withholdings:
       - Add a line with the created 0% Payment Withholding tax
       - Add a line with another Payment Withholding tax
- Create Payment
- Go to the payment

**Issue 1:**
When clicking on the first withholding line, a JS error is raised due to a missing index (i.e. currency_id).

**Cause 1:**
One of the fields has an aggregate sum function applied on it (i.e. amount_currency).
As it is a monetary field, the corresponding currency field is required in the view.

**Issue 2:**
When resetting the payment to draft, the withholding line with the 0% tax is deleted.
As the withholding table is not editable, it is not possible to add the line again.

**Cause 2:**
When the payment is reset to draft, the state of the associated journal entry is also set to draft and a "_sync_dynamic_lines" is triggered, which remove tax lines having a zero amount during the process.

**Solution 2:**
Keep all the lines with a Customer Payment Withholding tax as it is not possible to add a withholding line in the payment afterwards.
