//                          /cleanup total counts;
//   extra-formats          delete a video's audio in formats other than the
//                          channel's target, where the target is on disk;
//   wrong-format           delete every finalized audio file not in the target
//                          format, including failed-extract orphans;
//   failed-transcriptions  clear the channel's failed-transcriptions list, so
//                          "Transcribe missing" retries them (deletes no media).
// Each is the page's own action, so it keeps what the page's keeps: every
// sweep skips a do-not-clean video; "transcribed" also keeps the channel's
// keep-latest window and audio still awaiting diarization; every one deletes
// through the media tier's remover (removeMediaFile), never a bare link.
// `get cleanup <slug>` says what each would reclaim.
