Deleted: - PdfProcessingException: Obsolete, DevExpress exceptions now propagate naturally - SwissQrCodeNotFoundException: Moved to Application layer (feature-specific exception) Rationale: - PdfProcessingException was wrapping library exceptions unnecessarily - Better to let infrastructure exceptions propagate → middleware handles as 500 - SwissQrCodeNotFoundException is application-level concern, not domain
