Item Transit & Movement Tracking

[vivjd]

Goal:
Improve real-time visibility of items moving between the museum and external storage.

Tasks:

• Implement "In-Transit" status UI indicator on the Item Detail page. (This may have already been implemented, but ensure this works correctly).
• Create a "Mark as Arrived" workflow/button that updates Location ID.
• Ensure digital container logic works correctly: represent physical containers (Box/Tray) that can be assigned to a Location ID and tracked.

Acceptance Criteria:

• Volunteers can see if an item is currently "In Transit" before attempting to update its location.
• Clicking "Mark as Arrived" confirms receipt and clears the transit status.
• Ability to click a box as arrived, as well as single items.
• Physical-to-digital parity is maintained (moving a box updates all contained items).
