## Current behavior:
In Vietnam's Sales Tax Report, when unfolding until the minimum layer, the VAT now displays the value in negative

## Expected behavior:
The VAT value in the minimum layer should be consistent with the upper layers and kept positive

## Steps to reproduce:
- Install l10n_vn (l10n_vn_reports will install as well)
- Switch to VN Company
- With demo data, go to Invoicing / Reporting / Tax Report
- Change Tax Report (VN) to Sales/Purchase Tax Report (VN)
- Unfold the lines all the way to the minimum layer: VAT on sales of goods and services 10% -> INV/2026/00003
- Observe that the VAT 10% line is at negative, which is inconsistent with the Total line below

## Cause of the issue:
- In Odoo, tax journal items store tax_base_amount with the accounting sign (negative for sales). This is expected behavior
- However, Vietnamese VAT listing expects commercial amounts, which means sales bases need to be displayed as positive numbers

## Fix:
Normalized tax_base_amount sign in _query_tax_lines function before building the SQL query

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

- Opening Studio on a form containing a `Many2many` field using the `many2many_tags_email` widget crashes with an OWL prop validation error.

- **Steps to reproduce:**

1. Open any form view (e.g., Contacts) and enter `Studio`.
2. Create a new `Many2many` custom field on a model such as `res.partner` .
3. Set the field's widget to `many2many_tags_email` and save the customization.
4. Exit Studio and populate the field with one or more related records.
5. Open Studio again on the same form view.

This results in the following error:
```.js
Error: Invalid props for component 'RecipientTag': 'onDelete' is undefined (should be a value)

```

### Current behavior before PR:

- When opening Studio on a form containing a `Many2many` field with the `many2many_tags_email` widget, the field is rendered with `onDelete` set to undefined by `Many2ManyTagsField`. Starting from `saas-19.1`, the `many2many_tags_email` widget uses the new [RecipientTag](https://github.com/odoo/odoo/blob/saas-19.1/addons/mail/static/src/core/web/recipient_tag.js) component, which requires onDelete to be defined. As a result, Owl's prop validation fails when RecipientTag receives `onDelete = undefined`, causing Studio to crash with an Invalid props for component 'RecipientTag' error.

### Desired behavior after PR is merged:

- `RecipientTag` should allow `onDelete` to be optional so that it can also be used when the parent field does not provide a delete callback. This prevents the Owl prop validation error when opening Studio, while keeping the existing delete functionality unchanged for editable fields where onDelete is available.

Version:
--------
- 19.0+

Steps to reproduce:
-------------------
- Install `mrp` module
- Go to the setting enable `Lots & Serial Numbers` and `Storage Locations`
- Create a storable product tracked by Lots
- Configure a Putaway Rule for the product so it is stored in a
  sub-location
- Create a Bill of Materials for the product with at least one
  component
- Create and confirm a Manufacturing Order
- Increase the production quantity (e.g. using the "Change Production
  Quantity" wizard)
- Click **Generate Lot/Serial Number**
- Click **Produce All**

Issue:
------
Completing the Manufacturing Order raises:

    Invalid Operation
    You need to supply a Lot/Serial Number for product:
    - Product

even though a single lot should be sufficient for a lot-tracked
product.

Cause:
------
When the production quantity is increased, `change_prod_qty()` updates
the finished move's demanded quantity and re-reserves it through
`_update_finished_moves()`:

https://github.com/odoo/odoo/blob/154b49ec6be6230989ee4eb420e7f83b681ff520/addons/mrp/wizard/change_production_qty.py#L77

which calls `_action_assign()` on the finished move:

https://github.com/odoo/odoo/blob/154b49ec6be6230989ee4eb420e7f83b681ff520/addons/mrp/wizard/change_production_qty.py#L49

Since finished moves originate from the production location, they
bypass the normal reservation flow:

https://github.com/odoo/odoo/blob/154b49ec6be6230989ee4eb420e7f83b681ff520/addons/stock/models/stock_move.py#L2070

`_action_assign()` then tries to reuse the move's existing move line,
but the lookup requires `location_dest_id` to still match the move's
generic destination:

https://github.com/odoo/odoo/blob/154b49ec6be6230989ee4eb420e7f83b681ff520/addons/stock/models/stock_move.py#L2092-L2106

That existing line's `location_dest_id` was already redirected to the
putaway sub-location by the previous `_apply_putaway_strategy()` call
(at MO confirmation), so the lookup no longer matches and a second,
distinct move line is created and appended instead of the first one
being reused:

https://github.com/odoo/odoo/blob/154b49ec6be6230989ee4eb420e7f83b681ff520/addons/stock/models/stock_move.py#L2170

Later, clicking **Generate Lot/Serial Number** creates a single lot and
stores it on the production order's `lot_producing_ids`:

https://github.com/odoo/odoo/blob/154b49ec6be6230989ee4eb420e7f83b681ff520/addons/mrp/models/mrp_production.py#L1602

When **Produce All** is clicked, which trigger `button_mark_done()`  it calls
`_post_inventory()`:

https://github.com/odoo/odoo/blob/154b49ec6be6230989ee4eb420e7f83b681ff520/addons/mrp/models/mrp_production.py#L2227

which assigns that lot to the finished move through `move.lot_ids`:

https://github.com/odoo/odoo/blob/154b49ec6be6230989ee4eb420e7f83b681ff520/addons/mrp/models/mrp_production.py#L1925

Since `lot_ids` is declared with `inverse='_set_lot_ids'`, this write
triggers that inverse method:

https://github.com/odoo/odoo/blob/154b49ec6be6230989ee4eb420e7f83b681ff520/addons/stock/models/stock_move.py#L192

The current implementation of `_set_lot_ids()` only assigns the lot to
a single available move line, regardless of tracking type:

https://github.com/odoo/odoo/blob/154b49ec6be6230989ee4eb420e7f83b681ff520/addons/stock/models/stock_move.py#L656-L668

Since only one lot is ever generated for a lot-tracked product, only
the first finished move line receives a `lot_id`. The second move line
created after increasing the production quantity is left without one.

When `button_mark_done()` validates the finished move lines, it
detects that one of them still has no lot assigned and raises the
"Invalid Operation" error, even though a single lot is valid for the
entire production of a lot-tracked product.

Fix:
----
`action_generate_serial` produces a single lot for the whole production.
In `_post_inventory()`, right after the generated lot is set on
the finished move, propagate it to any remaining lot-less move lines
of a **lot**-tracked finished move.

# Issue
A traceback is shown

# Cause
The only thing I'm sure of is that the error is caused by this code :
https://github.com/odoo/odoo/blob/8759429547e42e9f63b15a7c80475be46ef437e2/addons/website/static/tests/tour_utils/lifecycle_dep_interaction.js#L18-L20

And that it is linked to `browser.localStorage`. I suspect it is due to some weird localStorage and
WysiwygAdapter interaction :
https://github.com/odoo/odoo/blob/d6a08b67a948f569a1ca893b6337ce50b4ef9f07/addons/website/static/tests/tours/widget_lifecycle.js#L53-L60

But I can't be sure because debugging tools do not seem to be working. See the inverstigation comment
in the associated PR for more information.

# Proposed Solution
Since this code is only used for this test :
https://github.com/odoo/odoo/blob/96a0a9a0332ae460973b6f01b461a0f7e3e2f7fa/addons/website/static/tests/tours/interaction_lifecycle.js#L14-L15

And the test directly parses from the `window.localStorage` :
https://github.com/odoo/odoo/blob/96a0a9a0332ae460973b6f01b461a0f7e3e2f7fa/addons/website/static/tests/tours/interaction_lifecycle.js#L50

We can use `window.localStorage` instead of `browser.localStorage`  as it fixes the issue

## Problem
When generating accrual entries for multiple sale orders, the stock variation lines would all show the same order name, even if the line belonged to a different sale order. This is caused by the `order` variable being reused from a previous loop.

## Solution
We will pull the order name directly from the order line in the current iteration.

## Steps to reproduce (Runbot v19)
1. Create a product with AVCO perpetual valuation
2. Make sure all accounts are configured properly (Income, Expense, Stock, and stock variation accounts)
3. Add units to the stock (it can be with an adjustment, as long as the product has a cost already set)
4. Create 2 separate sales orders for this product
5. Deliver both of the sales orders, do not invoice them
6. Now go to the Accounting App Review>Invoices to be issued
7. Select the 2 invoices that were created.

The Revenue accrual lines are correct, with each SO being referenced, but on the Stock variation lines, only the last SO selected will appear.
