feat: Adds device interface support info to joinroom response in MC websocket server.

Enhance MessengerBase and WebSocketServer functionality

Updated MessengerBase with new methods for action management and message posting, along with improved documentation. Introduced DeviceMessageBase for better message representation.

Enhanced MobileControlWebsocketServer to support device interfaces, adding DeviceInterfaceSupport to JoinResponse and a new DeviceInterfaceInfo class for detailed device information.
