fix(circulation): wrong statuts when cancelling an at_desk loan

[PascalRepond]

• Cancelling the request of an item at desk in an external library
  sent the item on shelf instead of in transit to house.
• The position of the item was deduced from the pickup location of
  the loan, which can be updated afterwards, or from the transaction
  library of the cancel operation, ie. where the librarian is.
• Use the transaction location of the loan instead, ie. the location
  of its last validate or receive action, both to determine the state
  of the cancelled loan and to validate the next pending request.
• Closes Cancelling a request can lead to wrong status #3663.

Walkthrough

The cancellation flow now determines an at-desk item’s location from the loan transaction location. It uses this location to validate pending requests and select cancellation or return transit. The precheck method no longer accepts circulation-location keyword arguments. Documentation, API tests, UI tests, REST tests, and circulation fixtures cover owning-library and external-library desk cancellations.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: 🟡 Moderate · up to 309e1

For some at-desk loans without a valid transaction location, cancellation can fail before the loan state is updated, leaving the request in an incorrect state. The guard should be added or the risk explicitly accepted before merging.

Explanation

The implementation uses the loan transaction location from the latest validation or receipt action to determine cancellation outcomes and pending-request validation. The added tests cover cancellation in an external library and cancellation in the owning library, matching issue #3663.
