refactor: Update Application layer for Codecrete Bill integration

- Change SwissQrCodeExtractionResult to use Bill + RawLines
- Update ISwissQrCodeProcessor to return tuple (Bill, string[])
- Add Codecrete.SwissQRBill.Generator v3.4.0 package reference
- Update ExtractSwissQrCodeQuery handler to use AutoMapper for Bill->DTO mapping
- Remove References property from query (not needed for QR extraction)
