Add boxes/crates management system to warehouse module
- Created boxes_crates table with 8-digit auto-generated box numbers - Added manage_boxes route and full CRUD operations - Implemented box status tracking (open/closed) - Added location assignment functionality - Integrated QZ Tray printing with barcode labels - Created manage_boxes.html with table, preview, and print features - Added 'Manage Boxes/Crates' card to warehouse main page - Boxes can be created without location and assigned later - Includes delete functionality for admin/management roles - Added box statistics display
