Add farm token field to widget + recalibrate lyric length to 20s/line

- widget: add Bearer token input (endpoint needs auth; empty token -> 401)
- engine: endpoint sings ~20s/line not 15s/line (12 lines measured 241s);
180s target now -> 9 lines
- farm token passed in start body -> MINIMAX_REMOTE_TOKEN env
