fix(test): update 11 failing tests to match refactored status tracking and API changes

- Update test_bulk_operations.py: Use FileProcessingStep instead of ProcessingLog for status filter tests
- Update test_file_listing.py: Use FileProcessingStep for processing status determination tests
- Update test_file_detail_endpoints.py: Replace hash_file with check_text in step summary test
- Update test_path_traversal_security.py: Import get_unique_filepath_with_counter from correct module
- Update test_process_document.py: Match current duplicate handling behavior (creates new record)
