feat: add Minimax Speech as alternative TTS provider for Reels

- Add minimax_config table (migration + schema + storage CRUD)
- Add GET/POST /api/minimax/config routes
- Pass tts_provider + minimax_api_key through ffmpeg service
- Add generate_tts_minimax() in Python using Minimax T2A v2 API
- Fall back to ffsubsync for subtitle sync (no WordBoundary events)
- Add Minimax config card in Settings page
- Add provider toggle (Edge TTS / Minimax) + French voices in new-reel
