feat(api): Add annotation endpoints to PdfOperationsController
- Add POST /api/pdf/operations/annotate (multipart/form-data)
- Add POST /api/pdf/operations/annotate (application/json with Base64)
- Create AddAnnotationMultipartRequest DTO (wrapper for 10+ form parameters)
- Create AddAnnotationBase64Command DTO (Base64 PDF + annotation parameters)
- Add unique operation names (AnnotateFromFile, AnnotateFromBase64) for Swagger
- Rename MergePdfsRequest -> MergePdfsBase64Request for clarity
- Add Name attributes to merge endpoints (MergeFromFiles, MergeFromBase64) to fix Swagger conflict
- Base64 FormatException wrapped in BadRequestException
