- Add GZIP compression for large export data (>2000 chars)
- Implement fallback QR generation with different error correction levels
- Add automatic decompression support in import functionality
- Improve error handling with fallback to text display
- Add localized error messages for QR code failures
- Add compression ratio logging for debugging
This fixes the 'Data too big' error when generating QR codes for
polycentric profile exports by automatically compressing large data
and providing multiple fallback mechanisms.
some small translation correction, some extended translations, where sentences had just one word as translation and add missing translations from the english strings.xml
