feat: add Docker deployment and CI/CD pipeline

- Multi-stage Dockerfile with standalone Next.js output (~386MB image)
- docker-compose.yml with health checks, resource limits, restart policy
- GitHub Actions workflow for auto-deploy on push to main
- Health check API endpoint at /api/health
- .dockerignore for optimized Docker builds
