Subject: [PATCH] chore(260329-x2a): add Dockerfile and .dockerignore for
 containerized deployment

- Multi-stage build: node:22-alpine for build, separate stage for serve
- Runs vite preview on port 4173 with host 0.0.0.0
- config.json mountable at runtime via -v /path/to/config.json:/app/dist/config.json:ro
