**Problem:**
Starting the timer on a task that is linked to a sale order item produces a timesheet that is not linked to it, and the Billable toggle is missing from the timer.

**Steps to reproduce:**
1. Install Timesheets and Sales
2. Open a task whose Sales Order Item is set
3. Start the timer from the Timesheets systray
4. Save it and open the resulting timesheet

**Current behavior:**
The Sales Order Item is empty. The Billable toggle only appears after removing and re-adding the task in the timer.

**Expected behavior:**
The timer is billable on the task's sale order item as soon as it is opened.

**Cause of the issue:**
`_get_timesheet_pre_filled_form_data` returns only `project_id` and `task_id`. The timer form merges that pre-fill over `timesheet_default_values`, which `lazy_session_info` computes once per session from `account.analytic.line.new()`
- a record with no project and no task, so `so_line`, `allow_billable` and `has_available_so` are all `False` in it. Because the pre-fill carries none of those keys, they keep the task-independent session values: the timesheet stays unlinked from the sale order item, and the Billable toggle stays hidden since it is displayed from `has_available_so`.

**Fix:**
The pre-fill endpoint is the only place that knows which task the timer is being opened on, so it is where the task-dependent values have to be resolved. Reading them off a new timesheet built with that project and task keeps the endpoint generic - it returns whatever `_get_aw_timesheet_fields_specification` declares, so the sale fields stay owned by sale_timesheet_enterprise rather than being named in timesheet_grid.

Dropping the session defaults instead was rejected: they are also the only source of `date`, `user_id` and `company_id` for the timer record, and removing them makes saving fail on the required Date field.

A running task/ticket timer can sometimes stutter, show negative values, and track the wrong elapsed time.

### Steps to reproduce

On a record with a timesheet timer (for example, a Field Service task):

1. Start the timer and let it run for about 15-20 seconds.
2. Stop it and confirm the dialog.
3. Start it again. This creates a new `timer_start`.
4. Reload the page.

The timer starts jumping every second between two different values. As it keeps running, it can even show negative values such as `00:00:-57`.

If the problem does not appear right away, repeat steps 2-4 a few times. It usually shows up after a few stop/start/reload cycles.

### Cause

The timer shown in the button bar is the `timer_start_field` widget. It starts a `setInterval` that updates a shared `TimerReactive` object once per second.

While a form is loading, Odoo renders it several times in a row (for example: a first render, another when the chatter is loaded, and another when the record data comes back from the server). Rendering a form builds all of its fields to produce the display, so each of these renders creates its own `timer_start_field`. Odoo keeps and mounts only the render that ends up on screen; the earlier ones are thrown away before being mounted.

The interval is started while the field renders, from the record observer set up in `setup`, before the field is mounted. So the fields that are later thrown away also start an interval. Those intervals keep running for the rest of the session. Each one updates the same shared `TimerReactive` object using the `timer_start` it was created with.

As long as every instance has the same `timer_start`, they all write the same value and the problem stays hidden. After the timer is stopped and started again, the old instances keep the old `timer_start` while the mounted one uses the new one. Every second they overwrite each other's value, so the timer jumps between two different elapsed times. When the instance with the newer `timer_start` writes right after one with an older start, it tries to show a smaller elapsed time than what is already there, and the subtraction in `TimerReactive` produces a negative number of seconds.

### Fix

Move the per-second timer update into a `useEffect`. The effect only runs after the field is mounted, and Owl automatically cleans it up when the field is unmounted or when `timer_start` or `timer_pause` change.

This means fields that are destroyed before they are mounted never start an interval, so only the mounted field updates the shared timer.

`onRecordChange` no longer starts or stops the interval. It only updates the displayed timer value to match the current record.

Steps to reproduce:

- Create a product with a bom and 2 operations
- Create an MO for 1 unit of that product
- Confirm the MO
- On the bom, delete the second operation and modify the first operation on anything else than the company, name or workcenter
- Go back to the MO, click the "Update Bom" button
> The second operation is not unlinked and the first operation is not
  updated

Cause of the issue:

The `action_update_bom` updates the move raws and operations of the MO via the `_link_bom`:
https://github.com/odoo/odoo/blob/f66614193cce18f5a3298d03ce7e5f29d54f07e9/addons/mrp/models/mrp_production.py#L1214-L1218 For draft MO's all the work of these updates is done via the compute methods and by deleting all the records unrelevant to the new bom: https://github.com/odoo/odoo/blob/f66614193cce18f5a3298d03ce7e5f29d54f07e9/addons/mrp/models/mrp_production.py#L2603-L2626 And, in that case all the workorders that are not linked to an operation of the bom are expected to be deleted. However, when the MO is not in draft, the update of operations is expected to be performed here: https://github.com/odoo/odoo/blob/f66614193cce18f5a3298d03ce7e5f29d54f07e9/addons/mrp/models/mrp_production.py#L2647-L2664 However, since the operation of the bom has been deleted, the workorder that is expected to be deleted is not linked to any operation and hence does not satisfy the condition to be deleted:
https://github.com/odoo/odoo/blob/f66614193cce18f5a3298d03ce7e5f29d54f07e9/addons/mrp/models/mrp_production.py#L2663-L2664 Concerning the non update of operations, it happens because the MO's operation are only updated on the three fields: `company_id`, `workcenter_id`, `name`:
https://github.com/odoo/odoo/blob/31df5033e31c193b4576ef37dfbc5fc683817bc5/addons/mrp/models/mrp_production.py#L2647-L2664 https://github.com/odoo/odoo/blob/31df5033e31c193b4576ef37dfbc5fc683817bc5/addons/mrp/models/mrp_production.py#L2628-L2629 However, many other cahnges can and are actually relevant.

Note:

Prior to commit 80e6ed658fb43584bc2fad673ca40d9af6cf0ab6 operations were archived on boms rather than deleted:
https://github.com/odoo/odoo/blob/4a5270218fe6fd7d30edb6d684b3340dc7423bab/addons/mrp/views/mrp_routing_views.xml#L53-L55 As such they would still be linked to an operation (but unrelated to the present values of the bom) and hence would fall into the condition of being unlinked from the MO.

Since the bom operations are no longer archived there is no way to determine if an operation used to be linked to a bom and we therefore need to chose between deleting all operations unrelated to the present bom or to keep them all (when the MO has been confirmed).

## Issue
When filtering projects using the "Timesheets >100%" filter, some projects with negative remaining hours (and with their `is_project_overtime` field set to True) won't be displayed, even though their expected hours are completed.

This happens with projects which have tasks set to the "Done" or "Cancelled" state. The timesheets entries in those tasks are not taken into account when searching using the "Timesheets >100%" filter.

## Steps to reproduce
1. Install *Task Logs* (`hr_timesheet`)
2. Create a Project P (with Timehseets enabled)
3. Set the allocated hours of the project to 3:00 (3 hours)
4. Create two tasks:
    - T1: State "In progress", and one timesheet entry of 2:00 (2 hours)
    - T2: State "Done", and one timesheet entry of 2:00 (2 hours)
5. Back to the project view, set the filter to "Timesheets >100%"
6. **Project P is not shown, even though the total time spent on the project is 4 hours, completing the allocated hours set on the project.**

## Cause
The `_search_is_project_overtime` method filters out the tasks in "closed" states (Done/Cancelled) when computing the amount of time spent on the project.

https://github.com/odoo/odoo/blob/126b5bdd1e85771549198976f8570cd2ff167608/addons/hr_timesheet/models/project_project.py#L103-L114

This does not match with the behavior of the `_compute_is_project_overtime`, which does not take into account the state of the tasks to determine the value of the field:

https://github.com/odoo/odoo/blob/126b5bdd1e85771549198976f8570cd2ff167608/addons/hr_timesheet/models/project_project.py#L85-L94

This leads to a confusing behavior, where a project can have its `is_project_overtime` field set to True, but will still not be shown when using the "Timsheets >100%", even though that filter is defined as `[("is_project_overtime", "=", True)]`.

The compute method was updated by https://github.com/odoo/odoo/commit/d4252825f52a3172420dcda0ea394e42da9f8853, but the related search method was left unchanged, leading to this slight incoherence between the two methods.

**Steps to reproduce:**
1. Install Accounting
2. Import a new invoice with more than 1000 lines (xlsx file found in ticket attachments)
3. Test the imported records

**Issue:**
- `RecursionError: maximum recursion depth exceeded`.

**Cause:**
- In a previous commit (3e32d7b9eace62dfa7334009707a93967906c726) aimed at fixing stale analytic distribution totals, the assignment loop in `_compute_discount_allocation_needed` was changed from iterating over `self` to `self.move_id.line_ids`.
- While this ensured all lines generated updated distribution ratios, it violated the compute logic: assigning values to records outside the current compute batch (`self`).
- By executing `line.discount_allocation_dirty = True` on external sibling lines, the method forced the ORM to trigger out-of-band `write()` calls. These writes re-triggered dependency checks (`_field_will_change`), which invoked the compute method again, leading to a recursive loop.

**Fix:**
1. Revert the assignment iteration back to `for line in self:`.
2. To preserve the intention of the previous commit (ensuring all lines recompute their shared distribution pool when one line changes), modify the method's `@api.depends` to be `move_id.line_ids.discount` and `move_id.line_ids.analytic_distribution`.

By declaring these relational dependencies, modifying a single line now batches all sibling lines into `self` from the start. This allows the lines to synchronize properly without triggering new ORM writes, eliminating the recursion.

Steps:
- Install sale_management
- Make sure you have 100 quotations with 1 activity each
- Open activity view
- Default pager displays `1-100/100`
- Activity count display `To-do 80`

ActivityController uses `useModel` which passes the raw `component.props` to
`model.load()`, including the limit from `ir.actions.act_window` (default 80).
This value ended up in `fetchActivityData` via `params.limit || this.initialLimit`,
overriding `ActivityModel.DEFAULT_LIMIT` (100).

The records list was not affected because `RelationalModel._getNextConfig` never
reads `params.limit` (limit is not a `SEARCH_KEY`), so it always loaded 100
records correctly. But `fetchActivityData` used 80, causing a mismatch between
the records shown and the activity counts in the column headers.

```js
export const SEARCH_KEYS = ["comparison", "context", "domain", "groupBy", "orderBy"];
```

The fix strips `params.limit` in `ActivityModel.load()` before passing params to
`fetchActivityData`, so it falls back to `this.initialLimit (100)`. The pager
`onUpdate` handler calls `fetchActivityData` directly with its own `params.limit`
and is not affected.

However, `ActivityController` never forwards `limit` to the model. This
is why we always have `ActivityModel.DEFAULT_LIMIT (100)` without taking
into account actions's limit. To fix this we have to add the limit via
`this.props.limit`, as `ListController`.

`useModelWithSampleData` already had the correct behavior by calling
`model.load(getSearchParams(props))` which filters out non-search params like
limit. In 19.0 useModel was updated to do the same, so the issue does not
exist there.

**Steps to reproduce**
- Open any MO
- Click on 'catalog'
- Click on the three dots button of any product
- Try to edit
-> Traceback: `"product.product"."state" field is undefined.`

**Cause**
The `move_raw_ids` field on the MO form sets a context with `form_view_ref: 'mrp.view_mrp_stock_move_operations'`, so that editing a component's `stock.move` line in place opens that dedicated view: https://github.com/odoo/odoo/blob/20db2910d16fa6ebd07794fb9ed3fb1c8f57b0fc/addons/mrp/views/mrp_production_views.xml#L411-L417 The 'Catalog' button lives inside that same field, and calls `action_add_from_catalog_raw`, which delegates to the mixin's `action_add_from_catalog`: https://github.com/odoo/odoo/blob/3dd41395e2e4205fa477eb474d4a4dba0a976154/addons/product/models/product_catalog_mixin.py#L17 Which conserve the `'form_view_ref'` from context: https://github.com/odoo/odoo/blob/3dd41395e2e4205fa477eb474d4a4dba0a976154/addons/product/models/product_catalog_mixin.py#L28 and that action requests its form view with `view_id=False`: https://github.com/odoo/odoo/blob/3dd41395e2e4205fa477eb474d4a4dba0a976154/addons/product/models/product_catalog_mixin.py#L25 Which will try to load `view_mrp_stock_move_operations`, since: https://github.com/odoo/odoo/blob/3dd41395e2e4205fa477eb474d4a4dba0a976154/odoo/addons/base/models/ir_ui_view.py#L3002-L3005 `_get_view` never checks that the resolved view's `model` matches the model it was asked for, so it returns `view_mrp_stock_move_operations`for the `product.product` model: https://github.com/odoo/odoo/blob/3dd41395e2e4205fa477eb474d4a4dba0a976154/addons/mrp/views/stock_move_views.xml#L41 https://github.com/odoo/odoo/blob/3dd41395e2e4205fa477eb474d4a4dba0a976154/addons/stock/views/stock_move_views.xml#L128 `state` doesn't exist on `product.product`, hence the crash.
