feat: fix CompactSeedQR binary QR code scanning with jsQR library

- Replace BarcodeDetector with jsQR for raw binary byte access
- BarcodeDetector forced UTF-8 decoding which corrupted binary data
- jsQR's binaryData property preserves raw bytes without text conversion
- Fix regex bug: use single backslash \x00 instead of \x00 for binary detection
- Add debug logging for scan data inspection
- QR generation already worked (Krux-compatible), only scanning was broken

Resolves binary QR code scanning for 12/24-word CompactSeedQR format.
Tested with Krux device - full bidirectional compatibility confirmed.
