Subject: Add JettingProxy relay, convert Xpl2Client to active connection model
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Insert a transparent TCP proxy between the controller and N clients:
- JettingProxy listens on 9110-9112 (controller) and 9210-9212 (clients)
- Broadcasts controller frames to all clients, forwards client→controller
- Independent KA_PING handling on both sides

Convert Xpl2Client from passive QTcpServer listener to active QTcpSocket
outbound connections with auto-retry. New QML API: host/commandPort
properties, connectToProxy()/disconnectFromProxy() replacing
startListening()/stopListening().
