fix(ocr): sync workflow steps with process_with_ocr replacing legacy azure step

- Update _compute_processing_flow to recognize process_with_ocr as the OCR
  stage and remap legacy process_with_azure_document_intelligence log entries
  for backward compatibility
- Normalize legacy OCR step name in _compute_step_summary log fallback
- Add process_with_ocr to REAL_MAIN_STEPS/REAL_STEPS in step_manager,
  file_status, and file_queries (keeping legacy name for old DB entries)
- Update retry logic in api/files.py to retry failed OCR via process_with_ocr
  (handles both step names as aliases)
- Fix process_document.py to log process_with_ocr as skipped (not azure step)
  for the local text extraction path
