Fix R128 and remaining ID fields to accept both JSON types

- Track.R128 and TrackShort.R128: float64 → JSONR128 (accepts both JSON number and object)
- All remaining primary ID fields: string → JSONID (accepts both JSON string and number)
  Fixed in: account, artist, clip, concert, feed, label, landing, metatag,
  music_history, pin, queue, radio, search, settings, supplement
