- Add CheckPdfAttachmentsQuery with dual input support (byte[] + Base64) - Add CheckPdfAttachmentsQueryHandler with IPdfProcessor integration - Add CheckPdfAttachmentsQueryValidator with FluentValidation rules - Add AttachmentCheckResult DTO for API response - Handler converts byte[] → MemoryStream for IPdfProcessor.CheckAttachmentsAsync() - AutoMapper maps AttachmentInfo → AttachmentCheckResult
