A comprehensive barcode scanning application for InvenTree inventory management. Features: - Multi-mode operation (Add/Update/Check/Locate stock) - Smart duplicate prevention when adding stock - Barcode scanning with automatic part code cleaning - Real-time server connection monitoring - Part information display with images - Debug mode for troubleshooting Fixes applied: - Fixed encoding issues with non-ASCII characters in barcodes - Fixed API response handling for list and dict formats - Implemented duplicate prevention using PATCH to update existing stock - Added comprehensive error handling and logging Includes test suite for verification of all fixes.
