grabowski ab0d1ae0db Initial commit: InvenTree Stock Tool v2
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.
