Pull request overview

This PR implements backend logic for item transit and movement tracking, specifically enabling boxes to be marked as arrived at a destination location. It adds a mark_as_arrived() method on the Box model that moves the box and syncs all contained items' locations and statuses, along with a corresponding API endpoint and tests. Additionally, it adds tests for the pre-existing complete-arrival movement request workflow.

Changes:

• Added Box.mark_as_arrived() model method that updates the box's location and syncs all contained items (location, is_on_floor, transit status) while creating ItemHistory records.
• Added POST /api/boxes/{id}/mark-arrived/ action on BoxViewSet with input validation (required location, non-existent location, same-location check).
• Added comprehensive tests for both the box arrival endpoint (BoxEndpointsTest) and the movement request arrival workflow (ItemMovementArrivalAPITest), plus formatting/line-length fixes across models and tests.
