Update Apache configuration and socket service for WebSocket support

This commit adds a ProxyTimeout setting for WebSocket connections in the Apache configuration, enhancing the server's ability to manage long-lived connections. Additionally, the socket service documentation is updated to clarify compatibility with both Apache and Nginx as reverse proxies. These changes improve the handling of real-time communication in the application.
