The system will crash with error when user tries to enable barcode scanner in settings.

**Steps to produce: -**
- Install `Inventory` module.
- `Inventory > configuration > products > Barcode Nomenclatures`.
- Delete the `Default Nomenclature` record.
- Go to settings uncheck `Barcode Scanner` and save settings.
- Now, again `enable` that and save.

Error: -
```py
ValueError: External ID not found in the system: barcodes.default_barcode_nomenclature

ParseError: while parsing /home/odoo/src/enterprise/saas-18.4/stock_barcode/data/data.xml:40, somewhere inside <record id='scale_up_alias_1' model='barcode.rule'>
            <field name='name'>Scale Up Receipt</field>
            <field name='type'>alias</field>
            <field name='pattern'>WH-RECEIPTS</field>
            <field name='alias'>WHIN</field>

            <field name='sequence'>0</field>
        </record>
```

**Root cause: -**
- At [1], the records use the ref of `default_barcode_nomenclature` which is defined in barcode module. So, when the ref is deleted and we are trying to use it then it gives error.

**Solution: -**
- This commit resolves the error by prevent the deletion of `default nomenclature`.

Steps to reproduce:
-----------------
1. Go to Timesheet → My Timesheet → List View → New OR Edit already filled time.
2. Change time in the Time Spent field.
3. Press Shift + Tab.

Observation:
-----------------
The focus changes, but the Time Spent field reverts to its old value instead of keeping the newly entered one.

Issue:
-----------------
- For new records, the component retrieves the value only from the state, which
is updated in the `onWillUpdateProps` lifecycle. This lifecycle triggers only on
saving or editing, not when simply changing focus.
https://github.com/odoo/enterprise/blob/e14b991927df14f41535e92dd01ea2ecac44a404/timesheet_grid/static/src/components/timesheet_display_timer/timesheet_display_timer.js#L123-L128

-  The same behavior occurs when editing existing records, leading to incorrect
value display.
https://github.com/odoo/enterprise/blob/e14b991927df14f41535e92dd01ea2ecac44a404/timesheet_grid/static/src/components/timesheet_display_timer/timesheet_display_timer.js#L31-L33

Solution:
-----------------
-  For new records, since the default value is 0, the fix makes the component
fall back to the updated record value if the state value is not yet available.

-  For existing records, if the timer is running, the timer’s value is
displayed. otherwise, the component falls back to the updated record value.

**Steps to reproduce:**
1. Install `l10n_mx` and `l10n_mx_edi`.
2. Create an invoice with:
   * Enable *CFDI to Public*.
   * Confirm, then send to SAT.
3. Create a credit note with:
   * *Usage* = `Returns, discounts or bonuses` (G02).
4. Download the generated XML for the credit note.

**Observed behavior:**
- The `<UsoCFDI>` tag in the XML shows `S01` (No fiscal effects).

**Expected behavior:**
- The `<UsoCFDI>` tag should show `G02` for credit notes under regime 616 when explicitly selected.

**Root cause:**
- For regime 616 (`Público en general`), the code always defaults to `S01`.
- The condition only allowed `G02` when refunding a global invoice (`is_refund_gi`), not for normal credit notes.

**Solution:**
- Allow `G02` usage to be preserved for credit notes (tipo_de_comprobante = 'E') even when `CFDI to public` is active, as this is now permitted by SAT regulations for fiscal regime 616.

### Steps to reproduce:
	- Open Field Service module.
	- Create a new task. In the Customer field, select “Bloem GmbH”.
	- Open the task’s project.
	- In the Invoicing tab, create a new line for any employee and any service.
	- Return to the task and in the Timesheets tab, add a new timesheet.
	- Click the Mark as done button.
	- Click the Sales order button.

### Cause:
When creating the sale order out of the fsm task we use _get_tax_included_unit_price to get the price of the SO line but we are passing the order currency twice to this method so it doesn't convert the price as when it checks the currency and the product_currency it found they are the same so no need to convert

### Fix:
We pass the product currency instead of the order currency in order to be able to convert the price according to the currencies

…ay change

**Steps to reproduce**
- Create a public holiday without a calendar during a work day.
- Create a leave for an employee overlapping the public holiday
for a time off type generating Timesheets. Validate it.
- Expected: on the day of the public holiday, no timesheet is
generated for the `hr.leave` to avoid duplication.
- Either delete the public holiday, or set a calendar on it
different than the one defined on the employee.

- Issue: the public holiday timesheet has been deleted, but its
deletion should've lead to the creation of the `hr.leave` timesheet
that we didn't create at the time the public holiday existed.

- Second issue: after that, change the calendar of the public holiday
to the same as the employee's. Still a missing timesheet.

**Solution**
We can use `_reevaluate_leaves` to find the leaves affected by changes
in public holidays.
`_generate_timesheets` then re-generates the timesheets as if the leave
was just validated (the call to `list_work_time_per_day` ignores the
already present resource.calendar.leave).
We also check missing public holidays timesheets to fix the second issue.

- Create an invoice with some products and post it
- Go to Accounting > Journal items and ser for the ones belonging to the invoice.
- Set the checkbox for the product sales one and set whatever tax grid (you'll have to reveal that column).
- Accept the changes.
- Now go back to the invoice.
- You'll see a new tracking message. Something like

Journal Item #1093 updated

- It contains a link and from that link you can go to the journal item form.
- In that form you can edit the *amount in currency* field.

Issue:

- If a user do so, it leaves inconsistent invoice amounts: totals aren't recomputed, analytic lines aren't recomputed either.

How it should behave:

- Amount in currency shouldn't be editable here. Mainly when the journal entry is already posted!

Description of the issue/feature this PR addresses:
This PR addresses a KeyError that occurs when attempting to generate a PDF quotation for multiple sales orders at once in Odoo. The issue arises when one or more selected orders do not have a valid PDF stream (e.g., due to missing data like order lines or incorrect templates). The error occurs because the system tries to access result[order.id]['stream'] for a sales order that doesn't have the stream generated, causing the server to fail.

Current behavior before PR:
Before this PR, when attempting to print the quotation for multiple sales orders, the system will throw a KeyError if any of the selected orders do not have a valid PDF stream generated. This can happen if a sales order is missing data (such as products or a client) or has an incomplete quotation template. The error prevents users from generating quotations for a group of sales orders, even if only one order is missing the necessary data.

Desired behavior after PR is merged:
After merging this PR, the system will check if the PDF stream exists before attempting to access it. If a sales order does not have a valid stream (due to missing data or other issues), it will be skipped without causing a server error. This allows users to print multiple quotations at once without the system failing due to one incomplete order. The feature will improve robustness when handling orders with missing or incomplete data and prevent unexpected crashes.
