Note: this PR is a forward of https://github.com/odoo/odoo/pull/229692

Refactor several POS core methods into overridable hooks so that l10n_be_pos_blackbox (v2) can intercept and extend critical flows to implement the new blackbox requirements.

point_of_sale:
- pos_store.js: extract posBackOnline(), openCashbox(), getSelfOrderToPrint(), and resetCashier() as dedicated methods; setCashier() now returns a boolean; preSyncAllOrders() now returns the orders array, and the sync loop skips an order when it returns falsy (allows blackbox to block premature syncing); add orderReceiptComponent class property so the receipt component can be substituted by submodules.
- order_payment_validation.js: extract canPrintReceipt getter (makes it overridable); fix absolute import path for error_handlers; fix typo "occured" → "occurred".
- pos_session.py: load product.template / product.product before account.tax in _load_pos_data_models to satisfy the blackbox data dependency order; include account_move id in the invoice list returned by the session sales-details report.

pos_hr:
- Split setCashier() into setCashier() + setCashierUpdateSession() so the session-update side-effect can be called independently by the blackbox during clock-in/out flows. Return true from setCashier() consistently with the base method.

pos_loyalty:
- Override displayPrice on order lines so gift-card trigger products always display a positive price, even when the order is a refund.

pos_restaurant:
- Refactor mergeOrders() into _mergeOrders() + _mergeLines() private helpers; add getLinesToMerge() hook so blackbox can filter which lines participate in a merge; mergeOrders() now returns the destination order; extract syncRestoredOrders() for overridability; replace the while-loop-with-guard-counter with a plain for-of loop.

pos_self_order:
- Add orderReceiptComponent property; extract handleKioskSessionStatusChange() so the kiosk status-change behaviour can be overridden by the blackbox self-order bridge.

## Problem
In shop floor, MOs with unplanned work orders get sorted before MOs that have planned operations, which contradicts the normal nulls last sorting for work orders.

## Solution
We will update the sorting logic in the MrpDisplay component to more gracefully handle falsy date_start values, sorting them to the end.

## Steps to reproduce (runbot 19)
1. Create 2 MOs with an operation (work order) involving a work center, we'll call them A and B.
2. Open Shop Floor and open the work center that the MOs' work orders belong to, and note they are ordered A, B (this is fine, neither are planned so the precedence falls back to id
3. Go back to MO B and plan it. This should give it precedence in Shop Floor
4. Under the work center in Shop Floor, note that the MOs are still ordered A, B, despite B's work order having a start date and A's work order not having one

To further motivate this being unintended, you can go to Manufacturing > Operations > Work Orders, and you'll see MO B's work order sitting at the top of the list.

Issue:
Sending Debit Notes to a tax authority can cause the following error: "ValueError: The following child node is not defined in the template: DebitNote/cbc:BuyerReference"

Steps to reproduce on any database with DIAN and Colombian localization:

  1. Create a new "Sales" type journal. Then, check the checkbox “Nota de Debito”.
  2. Find a res.partner with a ref field, or add a ref field to any partner.
  3. Make an invoice using the partner found in step 2. Ensure it uses a tax. Confirm it.
  4. Send that invoice to DIAN.
  5. Create a Debit Note for that invoice. Use the journal created in step 1.
  6. Add a product, price, and tax to the debit note. Confirm it.
  7. Send the debit note to DIAN.
  
Explanation:
The `_add_invoice_header_nodes` method on the AccountEdiXmlUbl_21 model adds a BuyerReference node unconditionally. (See account_edi_xml_ubl_21.py.) But the DebitNote XML template does not include a BuyerReference element (see ubl_21_debit_note.py). This caused a ValueError when assembling the XML for debit note documents.

Solution: The fix overrides this in the Colombian localization by clearing the BuyerReference value when the document type is "debit_note". That way, the node is omitted from the output.

### Issue:
When installing a new language on a database with `l10n_co_dian`, the DIAN email templates are not translated

Languages already installed when `l10n_co_dian` is installed are correctly translated, as the copy happens at that moment
Only languages installed afterwards are affected

### Cause:
The DIAN email templates are created dynamically via `_create_dian_mail_templates` as copies of the `account` templates
Because they are created at runtime, no translations exist for their XML IDs in the `l10n_co_dian` `.po` files
The `TranslationImporter` finds nothing to import for them

The fix hooks into `_load_module_terms` to sync translations from the source `account` templates to the DIAN ones whenever a new language is installed

`TranslationImporter.save()` is used without `force_overwrite`, so existing translations on `noupdate` records are never replaced
This is the standard way to push translations while preserving any manually modified values

### Notes:
Languages installed before this fix are not updated
Only newly installed languages will get the synced translations

### Steps to reproduce:
- Install `l10n_co_dian`
- Enable Developer Mode in Settings
- Install any language (e.g. `fr_FR`)
- Go in Settings > Technical > Email > Email Templates
- Search for DIAN and open Invoice or Credit Note

Before the fix, the DIAN invoice and credit note templates had untranslated name, description and body_html

Description of the issue/feature this PR addresses:

This error occurs when a model has properties and a `computed` field or `onchange` method depends on them.

`record.update()` is asynchronous. When an onchange or computed field is triggered, an additional request is sent to the server, increasing the time required to complete the update. See:

https://github.com/odoo/odoo/blob/727fe7412bb37c1664106625e248264d2aab6809/addons/web/static/src/model/relational_model/record.js#L1207-L1211

However, `PropertiesField` is rendered before the `update` is completed. See:

https://github.com/odoo/odoo/blob/727fe7412bb37c1664106625e248264d2aab6809/addons/web/static/src/views/fields/properties/properties_field.js#L86

As a result, the property labels are not yet available and the following traceback is raised:

`TypeError: Cannot read properties of undefined (reading 'getRootNode')
`
After this commit, the update is awaited before rendering PropertiesField, ensuring that the property labels are available.

**Steps to reproduce:**

1. Install the example module. [project_task_property.zip](https://github.com/user-attachments/files/29138424/project_task_property.zip)
2. Open or create a project task.
3. From the Action menu, click `Add Properties`.

The error is raised.

Steps to reproduce
------------------
1. Install l10n_ke_edi_oscu_pos.
2. Select the Kenyan company.
3. Enable eTIMS on the PoS.
4. Register the products inside a combo, but not the combo itself.
5. Sell the combo in the PoS.

Observation
-----------
We see a warning that the combo must be registered to eTIMS, and the order can't be validated.

What's happening
----------------
In the PoS a combo adds a 0 price parent line for the combo product, but the combo is not a real item to send to eTIMS, only the products inside it are, and (as per step 4) the combo is not registered.

`checkEtimsFields` sees the combo as not registered, so it raises the warning in `showUnregisteredProductsWarning` and blocks the payment in `validateOrder`.

Fix
---
In the backend, we skip sending the parent combo line to eTIMS, and on the frontend, we make the combo parent line not need eTIMS registration, so the warning and the block don't apply to it.

### Issue:
When invoicing partial quantities from a sale order, more DDTs than necessary are linked to the invoice

Since `l10n_it_ddt_ids` is computed and not stored, the incorrect links persist until the remaining quantities are invoiced, at which point the extra DDTs are moved to the new invoice

This creates inconsistencies in the generated XML, which references DDTs not actually covered by the invoice

### Cause:
The quantity allocation loop only checked whether there was remaining `move_qty` to consume, but never checked whether the invoiced quantity (`inv[0]`) had already been fully consumed

As a result, once all invoiced quantity was allocated, the loop kept iterating and linking additional DDTs from the sale order

### Steps to reproduce:
- Install `l10n_it_stock_ddt` with demo data
- Switch to the IT company
- Create a Warehouse
- Create a Product (Invoicing Policy: Delivered Quantities)
- Create and confirm a Sale Order (qty: 5) for that product
- Validate 3 partial deliveries of qty 1, creating a backorder each time
- Create the invoice, set the quantity to 2 and confirm

Before the fix, 3 DDTs were linked instead of 2

Current behavior before PR:
On mobile devices, the bank reconciliation dialog relied on the base kanban view
of account move line, which is difficult to handle and lacked contextual
information about the statement being reconciled.

Desired behavior after PR is merged:
The bank reconciliation flow on mobile uses a dedicated kanban view with a
simplified layout. An informational line is displayed above the main view,
showing the statement date, reference, and remaining balance for better context.

Changes implemented:
- Added a mobile-specific kanban view for bank reconciliation dialog.
- Displayed an information line above the kanban view with statement date,
  reference, and balance like desktop view for bank reconciliation dialog.
- Moved 'onSelectionChanged' to 'BankRecSelectCreateDialog' and shared it through
  'bankRecInfo', moved 'remainingAmountFormatted' into the state, and removed the
  duplicated getters from the list and kanban renderers.
- Kept the existing desktop layout and behavior unchanged.
- Added a HOOT test to check the mobile bank reconciliation dialog.

### Issue:
When creating an automatic reconciliation rule by assigning the same account to multiple bank statement lines, the rule incorrectly overrides the original payment reference of subsequent lines with the account name

This creates an inconsistent user experience
Using the "Set Account" button directly keeps the statement line payment reference as the journal item label
However, clicking the automatically generated reconciliation model button replaces that reference with the account name

Before the fix, clicking the automated rule button on a third matching line overrides its label with the account name instead of keeping its unique reference

### Cause:
In `_create_reconciliation_rule`, when an automatic model is generated, the dictionary used to create the counterpart line explicitly set `label` to `rule_data['account'].name`

When a reconciliation model line has a specific label defined, Odoo uses it to replace the statement line `payment_ref` on the generated counterpart move lines
Removing this default value allows the system to fall back on the original payment reference

### Steps to reproduce:
- Install `account_accountant`
- Go to the Bank Reconciliation widget from the Accounting Dashboard
- Create 2 statement lines without partners (e.g., Ref: "Test Ref 1" and "Test Ref 2")
- Set the same account on both lines using Set Account
- This automatically creates a Reconciliation Rule named after the account
- Create a 3rd statement line with a matching reference (e.g., "Test Ref 3")
- Click the newly available automatic reconciliation button for this line

Before the fix, checking the generated entry label shows the account name instead of "Test Ref 3"
To check unfold the details, click on the pencil icon of a line

When we scan a gs1 barcode that has in his lot a special character and start with 10, odoo will not be able to retrieve it from the db.

**Steps to reproduce**

* In settings activate:
  - Lots & Serial Numbers
  - Units of Measure & Packagings
  - Storage Locations
  - Barcode Scanner : GS1 nomenclature
* Create a Product tracked by lot with
  - barcode: 00001234567895
* Add on hand quantity:
  - 100 kg in lot : 10002002303-4
  - 100 kg in lot : 11002002303-4
* Go to barcode>Operation>Internal Transfer>New
* Scan 02000012345678951010002002303-4#3100000100 meaning:
  - 02 following 14 characters are the product barcode
  - 10 following characters are the lot number
  - "#" separator
  - 3100: means the units are kilograms, 
  - 00100 means 100 units. 

-> if you check with the edit button the lot was not found (if you click on validate it will trigger an UserError for missing lot)

**Observation**

When scanning the GS1 barcode it will call onBarcodeSubmitted->onBarcodeScanned where we will execute processBarcode: https://github.com/odoo/enterprise/blob/8030b105d3fce1eef9b8965a2bfc37195f71723c/stock_barcode/static/src/components/main.js#L387 Where we will deconstruct the barcode into his component en retrieve from the db the relevant data: https://github.com/odoo/enterprise/blob/8030b105d3fce1eef9b8965a2bfc37195f71723c/stock_barcode/static/src/models/barcode_model.js#L709-L717

- First the barcode is parsed, identifiers are erased and each section is separated, the variable with our lot number only has the lot number in it, the identifier (10) is not included, BarcodeObject.forBarcode(bc) -> new BarcodeObject -> parser.parse_barcode: https://github.com/odoo/enterprise/blob/8030b105d3fce1eef9b8965a2bfc37195f71723c/stock_barcode/static/src/barcode_object.js#L14
- Check if the data is in the cache, if not, set it to retrieve after
- Retrieve missing data getMissingRecords : https://github.com/odoo/enterprise/blob/8030b105d3fce1eef9b8965a2bfc37195f71723c/stock_barcode/static/src/lazy_barcode_cache.js#L349 From here we will get a call to get_specific_barcode_data for each element: https://github.com/odoo/enterprise/blob/8030b105d3fce1eef9b8965a2bfc37195f71723c/stock_barcode/controllers/stock_barcode.py#L176 In the case of the stock.lot since it has a symbol and it's not only digit it will skip the gs1 nomenclature domain converter (it will not become 'ilike' and stay with 'in'): https://github.com/odoo/enterprise/blob/8030b105d3fce1eef9b8965a2bfc37195f71723c/stock_barcode/controllers/stock_barcode.py#L182-L197 We will do the search:
https://github.com/odoo/enterprise/blob/8030b105d3fce1eef9b8965a2bfc37195f71723c/stock_barcode/controllers/stock_barcode.py#L205 during which we will retrieve specific query from the stock.lot module : https://github.com/odoo/odoo/blob/8d14665af5acf1bd391d05a5048dc701986e8b15/odoo/orm/models.py#L1408 Where, since it's a GS1 nomenclature, we will preprocess the agrs: https://github.com/odoo/enterprise/blob/8030b105d3fce1eef9b8965a2bfc37195f71723c/stock_barcode/models/stock_lot.py#L14 
-> Since our barcode start with a 10, it will erase it, which lead to a miss in the search.


It will also avoid further searches since we avoid multiple search on the same elements (added in missingBarcodeKeyCache in getMissingRecords). https://github.com/odoo/enterprise/blob/c6d18a7a92092ffdf96f4569a70e95bdc276441c/stock_barcode/static/src/lazy_barcode_cache.js#L294-L298

**Problem:**
When an attendance has overtimes across multiple days, those overtimes can
overlap when calculating their intervals.

There will always be rounding errors since only the durations are saved to 3
decimals, but this is normally fine since the durations are accumulated when
calculating the next interval.

However, on a day boundary in the employee timezone, the end of the interval is
forced to the end of day, which incidentally removes the rounding error. This
causes the overlap when calculating the next interval since its start will be
based on the rounded duration, not the actual end of day.

**Steps to Reproduce:**
- Configure an overtime rule where >8 hours is considered overtime, and a
second rule applies to non-working days
- Set Overtime Rule on employee "Anita Oliver"
- Set employee work entry source to "Attendances"
- Create an attendance that exceeds 8 hours in a day and crosses into a
non-working day and creates enough of a rounding error (see unit test)

-> Traceback error:
`ValueError: Expected singleton: hr.attendance.overtime.line(1, 2)`

**Solution:**
Add an additional check to ensure the overtime cannot start on the previous
day.

### Steps to Reproduce
1. Activate l10n_dk
2. Have a Danish customer contact where the eInvoice format is OIOUBL 2.1
3. Create an invoice with them as the partner and make sure that the line has a tax and a discount
4. Download the XML and try to validate

### Description of the issue/feature this PR addresses: 
**Issue:** When sending customer invoices with discounts on lines with the OIOUBL 2.1 format, the generated XML fails official Nemhandel validation. The schematron rejects the file because line-level allowance blocks do not declare their tax classifications. Specifically, this violates mandatory compliance rule [F-LIB226], which says that one `TaxCategory` class must be present inside every `cac:AllowanceCharge` block on a line item.

**Solution:**
By using the target dictionary array after the base framework is generated, it gets the line's tax information using native grouping functions. It then injects the `cac:TaxCategory` sub-block directly into each array item mapping.

### Current behavior before PR:
When a product line includes a discount, Odoo outputs a standard line-level `cac:AllowanceCharge` block. It does not include the necessary tax information. This incomplete XML causes Nemhandel to throw an error.

### Desired behavior after PR is merged:
Every line-level discount allowance generated for a Danish invoice will include the relevant tax classification metadata downstream into the XML. This will ensure that it is accepted by Nemhandel.

When a user chooses the "Double Opt-in" template (or others using
`_create_records_with_xml_ids`), the system creates records like the
"Confirmed contacts" list and a server action. It also adds an
`ir.model.data` entry for them under the module, but sets
`noupdate=False`.

The problem is that during a module upgrade, Odoo's cleanup process
(`_process_end`) deletes any record marked `noupdate=False` if it
wasn't "reloaded" from a file. Since these records are created
manually in the code and aren't in any XML file, they never get
reloaded, so Odoo just deletes them and the records they point to.

By setting `noupdate=True` when these rows are created, we tell
the system to leave them alone during upgrades. Since these only
exist at runtime and don't have a data file, we don't need to
worry about them being updated later anyway.

The helper was added in
https://github.com/odoo/enterprise/commit/fd98660e352512e0b74d91958707687978154833.

Steps to reproduce:
1. Install Marketing Automation
2. Go to Campaigns > New and pick the "Double Opt-in" template, then save
3. Confirm the "Confirmed contacts" mailing list and server action exist
4. Go to Apps and Upgrade Marketing Automation
5. Try to find the mailing list and server action again

=> They disappear after the upgrade.

opw-6140191

### Steps to reproduce:

- In the settings enable: "Storage Locations" and "Consignment"
- Create a storable product and put 1 unit in stock with a set owner
- Go to the barcode app > Operations > Delivery Orders > New
- Scan your product and validate
#### > The owner was not set on the stock move line so that a new quant was created and updated in stock rather than using the available unit.

### Cause of the issue:

The mechanism of prefilling an owner or a package in the barcode app is currently gate-kept behind the existence of a lot name: https://github.com/odoo/enterprise/blob/0be4f71de3420fb9b72fd4e70d48c6cbbbc0ecb4/stock_barcode/static/src/models/barcode_model.js#L1382-L1407
However, the option also make sense for none tracked products.

### Note:

Performing the flow form the backend and adding quantity will generate the move line by setting the owner if possible since the quantity of a move is set via the back end, move lines are generated by looking at the existing quant data's:
https://github.com/odoo/odoo/blob/5d61c03b33c9a915684dd59656f8be7612956dd1/addons/stock/models/stock_move.py#L2364 https://github.com/odoo/odoo/blob/5d61c03b33c9a915684dd59656f8be7612956dd1/addons/stock/models/stock_move.py#L2328-L2330
Setting the same owner on the new move line as on the quant we are going to reserve:
https://github.com/odoo/odoo/blob/5d61c03b33c9a915684dd59656f8be7612956dd1/addons/stock/models/stock_move.py#L2337 https://github.com/odoo/odoo/blob/5d61c03b33c9a915684dd59656f8be7612956dd1/addons/stock/models/stock_move.py#L1715

Additional subtelties appearing when prefilling for non tracked product:

1. Currently the available quantity is not taken into account to determine if the the value provided to the prefilled is actually
relevant, in particular if there is a quant with an available quantity of 0, it will be used as a valid value to prefill and it will parasit the prefill that could be done by other quants.

2. The location source used to determine the quants taken into account is not set on the first scan since the scan is performed without any existing line:
https://github.com/odoo/enterprise/blob/4f0d25f9fe4ca8ff1b0ecd7900899a2a246ba888/stock_barcode/static/src/models/barcode_model.js#L1387
> This was not problematic with respect to tracked product since the product needs to be scanned prior to the lot, hence there is always a current line when the the lot is scanned.
