Subject: [PATCH] Enhance socketService configuration for WebSocket upgrades

This commit updates the `socketService.js` file to improve WebSocket upgrade handling by adding two new configuration options: `allowEIO3`, which permits WebSocket upgrades without an Origin header, and `serveClient`, which disables serving the client bundle. These changes enhance compatibility with reverse proxies and optimize the WebSocket connection process.
