fix: Docker one-click deployment — all deps bundled, native modules, health check

- Multi-stage build: builder installs backend + frontend deps, compiles
- Production stage: npm ci --production rebuilds native modules (opus, sqlite3)
- FFmpeg bundled via ffmpeg-static (no apt install ffmpeg)
- .dockerignore prevents node_modules/dist from being copied
- docker-compose uses host network for TS3 UDP connectivity
- Named volume for persistent data
- Health check endpoint
