Refactor Docker setup for Astro SSR application and Nginx reverse proxy

- Updated docker-compose.yml to define services for the Astro SSR application and Nginx reverse proxy, including health checks and environment variables.
- Modified Dockerfile to implement a multi-stage build process, optimizing dependency installation and production setup.
- Enhanced nginx.conf with improved proxy settings, security headers, and caching strategies for static assets, ensuring better performance and security.
