Fix: Add missing printing module table and improve database management error handling

- Added order_for_labels table to init_db.py (printing/labels module)
- Fixed fetch API calls in database management to properly check HTTP response status before parsing JSON
- Prevents 'Unexpected token' errors when server returns HTML error pages instead of JSON
- Improved error messages for better debugging (shows HTTP status codes)
- All 10 database management API endpoints now have proper error handling

init_db.py
