Add deferred save for prize reordering in admin

- Remove auto-save on drag-and-drop (prevents UI jumps)
- Store prize order changes locally
- Show warning banner with unsaved changes
- Add Save and Cancel buttons
- Only trigger API call when user clicks Save
- Add translations for unsaved order messages
