feat(minimax): add Group ID support to fix rate limit quota

Pass GroupId query param to Minimax T2A v2 API — required for paid
plan quota allocation. Without it, Minimax defaults to (0/0 used).

- shared/schema.ts: groupId field on minimaxConfig table
- server/migrate.ts: ADD COLUMN IF NOT EXISTS group_id
- server/routes/reels.ts: fetch and pass groupId alongside apiKey
- server/services/ffmpeg.ts: minimax_group_id in request interface/body
- ffmpeg-service/main.py: GroupId in URL, threaded through all call sites
- client/src/pages/settings.tsx: Group ID input in Minimax settings card
