Fix failing config test and clean up lint warnings

- tests: align test_default_config_ocr_language with intentional
  omission of ocr.language from defaults (auto-detected on first run
  by services.settings._load_language_settings)
- nautilus extension: sort imports (ruff I001)
- odf_builder, tsv_odf_converter: drop stale noqa directives for
  rules not enabled in pyproject
- window_actions: rename loop variable to avoid PLW2901 reassignment
