Introduced endpoints for embedding attachments in PDFs and converting between standard PDFs and PDF/A formats. Added `PdfAttachmentController` and `PdfConversionController` with multipart/form-data and Base64-based support. Implemented commands, handlers, and validators for these operations. Extended `IPdfProcessor` with methods for adding attachments and PDF/A conversion. Partially implemented functionality in `DevExpressPdfProcessor`, including `ConvertFromPdfAAsync`. Added `attachment.xml` and `withoutAttachment.pdf` as resources for testing. Marked endpoints as `[Obsolete]` to indicate incomplete implementation. Improved validation and error handling for commands.
