## **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.

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.
