task modal: audio info panel for Get Lyrics (title/artist/length/lyrics)

Display-only panel at the top of the Get Lyrics run-task form (single file only):

- Backend: GET /file-browser/audio-meta?path= — ffprobe format tags + duration,
  plus a second probe for embedded lyrics (USLT/SYLT/lyrics* keys, case-insensitive).
  Returns { title, artist, duration, hasLyrics }; tolerant of missing tags/probe
  failures.
- Client: files.audioMeta(path) + AudioMeta type in useFilesAPI.
- TaskRunnerModal: prefetch audioMeta for get-lyrics single-file runs (bypasses
  the hasTrackPickers early-return, error-tolerant), and render AudioMetaPanel
  above TaskInputForm — title/artist + a muted length + Lyrics: Yes/No chip,
  filename fallback. Directories + other tasks unaffected (no panel, no probing).

Verified ffprobe logic on a real embedded-lyrics file. tsgo clean; formatted.
