Remove FormatException/ArgumentException handling:
- These are framework exceptions, not application-specific
- May come from internal libraries (false positives for 400 Bad Request)
- Controllers now wrap Base64 conversion with BadRequestException explicitly
Remove PdfProcessingException handling:
- Exception type removed (obsolete)
- DevExpress exceptions now propagate naturally → 500 Internal Server Error
Current exception mapping:
- ValidationException (FluentValidation) → 400 Bad Request
- BadRequestException (custom) → 400 Bad Request
- NotFoundException (custom) → 404 Not Found
- SwissQrCodeNotFoundException (custom) → 404 Not Found
- All others → 500 Internal Server Error
