feat(ci): add GitHub Actions workflow for production deployment

Introduce `deploy.yml` to automate deployment to production on `prod` branch push. Includes setup for Node.js, pnpm caching, linting, building, and Docker Compose deployment. Update `docker-compose.prod.yml` to use environment variables for enhanced configurability.
