Consolidated DTOs under `DocumentService.Application.Common.DTOs.Requests`
to centralize and align them with the application layer. Introduced
`PdfBase64RequestBase` to encapsulate shared properties, reducing
redundancy across request DTOs. Updated controllers, clients, and tests
to use the new DTO structure. Removed redundant DTOs and cleaned up
unused namespaces and comments. Improved documentation and ensured
consistent naming conventions across the codebase.
Introduced multiple interfaces and DTOs to support a wide range of
PDF-related operations, including attachment handling, conversion,
validation, annotation, stamping, and metadata extraction.
Key changes:
- Added `DocumentServiceClientOptions` for HTTP client config.
- Introduced `IPdfAttachmentClient` for attachment operations.
- Added `IPdfConversionClient` for PDF/A conversion (marked obsolete).
- Added `IPdfOperationsClient` for merge, annotate, and stamp ops.
- Introduced `IPdfValidationClient` for PDF and PDF/A validation.
- Added `ISwissQrCodeClient` for Swiss QR Code extraction.
- Added `IZugferdClient` for ZUGFeRD detection and extraction.
- Created request DTOs for Base64-encoded operations.
- Added enums for annotation, stamp, and validation configurations.
These changes provide a flexible and extensible foundation for
interacting with PDF documents, supporting both multipart and
Base64-encoded inputs, and ensuring type safety with enums and records.
