- Add comprehensive logging to all pipeline retry branches (process_document, process_with_azure_document_intelligence, extract_metadata_with_gpt, embed_metadata_into_pdf)
- Add original_file_path as 3rd fallback for embed_metadata_into_pdf (checks: local_filename, processed_file_path, original_file_path, workdir/tmp fallback)
- Include all checked paths with existence status in 400 error responses for easier debugging
- Add enhanced logging to upload task retry path showing which processed file paths were checked
- Log successful file path when found
- Add comprehensive test suite covering new logging and fallback behavior
