feat: improve reverse proxy setup for production

Updated README with detailed instructions for setting environment variables via a .env file. Added sample Caddyfile for reverse proxy configuration and systemd service files for managing the tracker and application. These enhancements streamline deployment, especially in production environments, by providing clear guidance and automation options.
