## **Steps to reproduce:**

1. Create a Service product with Create on Order set to Task and Project set to Field service project.
2. Create a Sales Order containing a storable product and a service product.
3. Confirm the Sales Order to generate the project, task, and delivery order.
4. Validate the delivery order.
5. Create and validate a return for the delivery.
6. Create a return of the return to deliver the products again, but do not validate this new delivery.
7. Open the related task and click on Mark as Done button.

## **Issue:**

In a delivery -> return -> return of return workflow, the stock move goes into this code
https://github.com/odoo/enterprise/blob/59b86f106862c3a364ba633a1580d9051f2fe7ca/industry_fsm_stock/models/project_task.py#L89-L90 the traversal repeatedly revisits the same stock moves through move_dest_ids, causing the loop to alternate between the same move recordsets indefinitely. As a result, the loop never terminates, eventually exhausting the memory and raising a `MemoryError`.

## **Solution:**

Track the stock moves that have already been visited and continue the traversal only with unseen destination moves.

Steps to reproduce:
-------------------------------------------------
1. Install the `sale_project` module
2. Create a test user with Project User rights
3. Create a Project Role with the Created User as a Team Member
4. Create a Template Project as follows:
    * Add one task to the template project
    * Add the created Project role to the Task
5. Create a Service Type Product with:
    * Create on order: Project
    * Project Template: Created Template
6. Archive the Created User
7. Create and Confirm the Sale Order with the Created Product

Observation:
-------------------------------------------------
The generated task is assigned to the archived user, although the archived user is no longer part of the Project Role.

Issue:
-------------------------------------------------
While creating Project and Tasks from template, the context disable active record filtering (e.g., `active_test=False`), causing the assignment logic to fetch both active and inactive/archived users linked to the role. https://github.com/odoo/odoo/blob/8ec646e51497b38d34ea59296e0fc8644a50ee3a/odoo/orm/models.py#L4868

After that, during the `copy_data` method, It takes all the users from the roles without checking weather user is active or not
https://github.com/odoo/odoo/blob/8ec646e51497b38d34ea59296e0fc8644a50ee3a/addons/project/models/project_task.py#L890-L904

And even if we pass only Active users from this method, on moving further, it reassigns the users from roles without checking the Active field of the user

https://github.com/odoo/enterprise/blob/5abb147f9bf725daafc202d8259a5bb8a9b78d94/project_enterprise/models/project_task.py#L501-L503

https://github.com/odoo/enterprise/blob/5abb147f9bf725daafc202d8259a5bb8a9b78d94/project_enterprise/models/project_task.py#L544-L553

Due to this, the Archived User is also assigned to the tasks from the project roles

Solution:
-------------------------------------------------
Apply a `filtered('active')` check directly on the project role's users `(role.user_ids)` within the core task-copying logic in both `project` and `project_enterprise` modules. This ensures archived users are universally excluded from task assignments during template copying, regardless of what triggers the template instantiation.

### Steps to Reproduce:
1. Go to Helpdesk and create an SLA
2. Create a new Ticket
3. Use Studio to add the field `sla_reached`
4. Apply the SLA
5. Notice that the field is True

### Description of the issue/feature this PR addresses:
**Issue:** The `_compute_sla_reached` method in on `helpdesk_ticket.py` determines whether an SLA has been reached by checking if `exceeded_hours` is less than 0 on its `helpdesk.sla.status` records. Since every newly assigned SLA has a future deadline, `exceeded_hours` starts as negative (AKA <0), so the ticket is immediately flagged as `sla_reached = True` before any progress has been made. Conversely, a ticket that reaches its target stage after the deadline has `exceeded_hours >= 0`, so it's incorrectly flagged as `sla_reached = False` even though the SLA target was genuinely reached (it was just late).

**Solution:** Change the domain in `_compute_sla_reached` to check `reached_datetime != False` instead of `exceeded_hours < 0`, matching the field already listed in the method's `@api.depends` and the same field `_sla_reach()` sets when a ticket enters its target stage. This makes `sla_reached` reflect actual stage progression rather than a time-remaining calculation.

### Current behavior before PR: 
A newly created ticket with a pending SLA shows `sla_reached = True` and `sla_success = True` immediately upon creation, before the ticket has moved to any target stage. SImilarly, a ticket that reaches its target stage after the SLA deadline is incorrectly marked `sla_reached = False`.

### Desired behavior after PR: 
`sla_reached` is False on ticket creation and only becomes True once the ticket actually enters the SLA's target stage. Lateness continues to be tracked separately and correctly via `sla_reached_late`

The original issue coudn't be reproduced. But based on what was reported on the ticket, this should improve the behavior of the order receipt.

Steps to reproduce:
-------------------
* Setup the l10n_ke module in 'production' mode
* Make an order in POS and validate it
> Observation: The receipt doesn't contain the SCU information and QR

Why the fix:
------------
Based on the receipt screenshot shared on the ticket (from Odoo 19.3) we can see that some informations are shown on the ticket. The information shown are the one received from the etims api, it means the call went through and the response was received.

As the qrCode URL only needs `l10n_ke_oscu_signature` to be generated, we can assume that if this field is set we can safely generate the URL and generate the QR code.

https://github.com/odoo/enterprise/blob/ee7e6894ed313db844aeff5ba5e19de3ad94898e/l10n_ke_edi_oscu_pos/models/pos_order.py#L252-L256

Based on this assumption we can change the condition to return the URL or not based on the presence of `l10n_ke_oscu_signature` instead of the state of the order being `sent`.

In 19.0, the receipt is showing no info at all (when 19.3 is showing some info like the signature). This is also happening because the URL was falsy. And when that is the case we do not show any SCU information

Steps to reproduce
---
1. Configure a `delivery_easypost` shipping method using the DHL Express carrier.
2. On an international delivery, use Put in Pack to create two or more packages.
3. Validate the delivery.

Issue
---
Validation is blocked with `DHLExpress: rate_error -- DHLExpress multi-shipment rate includes this shipment.`

For an EasyPost multi-shipment order, DHL Express returns the aggregate rate on the first (master) shipment only and adds an informational `rate_error` on the order stating that this rate already covers the whole order, so the remaining shipments carry no rate of their own. The message is not a real error, but `send_shipping` raises on any carrier message whose type is not exempt: https://github.com/odoo/enterprise/blob/534b42def8ae5dc884da4398377f828c49557d6e/delivery_easypost/models/easypost_request.py#L359-L364

`_post_process_ship_response` already detects and clears exactly this harmless message, but only for a hardcoded carrier allowlist introduced in a2de5bc5a14 (`Purolator`, `DPD UK`, `UPS`) that was never extended to DHL Express, so for DHL Express the message survives, reaches the raise, and aborts an otherwise valid shipment: https://github.com/odoo/enterprise/blob/a2de5bc5a14f99b8674c3ee234e4d221b406da0f/delivery_easypost/models/easypost_request.py#L416-L434

`DHL Express` is added to that allowlist so the harmless multi-shipment `rate_error` is posted on the picking and cleared instead of raised. The guard still requires a single `rate_error` carrying the "multi-shipment rate includes this shipment." text with the rate present only on the master shipment, so genuine DHL Express errors keep blocking validation.

Problem:
On a flexible working schedule, a time off of a few hours (neither a full nor a half day) was treated as a full day off. The Attendance list then reported the whole day's attendance as overtime, and the Time Off gantt grayed out the entire day instead of only the leave's hours.

Steps to reproduce:
1. Give an employee a flexible working schedule (e.g. 8h/day) with an overtime ruleset based on the contract's expected hours.
2. Record a 2-hour time off, then an 8-hour attendance on the same day.
3. Observe the attendance reports 8 hours of overtime instead of 2.

Current behavior:
A partial time off makes the whole day count as extra hours.

Expected behavior:
Only the hours actually taken off reduce the day's expected hours.

Cause:
For a flexible schedule, _handle_flexible_leave_interval expands a leave to the whole day. The override already narrows full-day and half-day leaves, but any other number of hours fell through to that full-day expansion. The expanded interval is subtracted from the day's expected hours in _work_intervals_batch, so they drop to zero and every worked hour becomes overtime.

Fix:
A leave of an arbitrary number of hours should only remove the hours it actually covers, so it keeps its requested interval instead of being stretched to the whole day.
