test(release): adapt suite to explicit ReleaseKnowledge injection

- test_release.py / test_release_fixtures.py: module-level
  _KB = YamlReleaseKnowledge() + thin _parse(name) helper threading it
  into parse_release. test_show_folder_name_strips_windows_chars renamed
  to test_show_folder_name_uses_already_safe_title to reflect the
  Option B contract (caller sanitizes via kb.sanitize_for_fs).
- test_detect_media_type.py: same _KB pattern, all
  detect_media_type(parsed, path) calls now pass kb.
- test_filesystem_extras.py: find_video_file(path) calls now pass kb.
- test_enrich_from_probe.py: _bare() helper adds the new
  title_sanitized field.
- test_resolve_destination.py: drop _sanitize import + TestSanitize
  class (helper deleted), add tmdb_title_safe arg to
  _resolve_series_folder calls.
