This PR updates the default Zephyr configuration for the Arduino Portenta H7 to properly support multiple simultaneous TCP connections.
The previous configuration used conservative defaults that limited the network stack's ability to handle more than one active socket alongside the listening server.
This PR resolves the issues arising from #227, where only a single client could connect at a time when using the
AdvancedChatServer.inoexample, preventingConnection refusederrors for subsequent clients.
