feat: Add Set Orders on Boxes feature with debouncing and page refresh

- Created warehouse_orders.py module with 8 order management functions
- Added /warehouse/set-orders-on-boxes route and 7 API endpoints
- Implemented 4-tab interface: assign, find, move, and view orders
- Changed assign input from dropdown to text field with BOX validation
- Fixed location join issue in warehouse.py (use boxes_crates.location_id)
- Added debouncing flag to prevent multiple rapid form submissions
- Added page refresh after successful order assignment
- Disabled assign button during processing
- Added page refresh with 2 second delay for UX feedback
- Added CP code validation in inventory page
- Improved modal styling with theme support
- Fixed set_boxes_locations page to refresh box info after assignments
