Refactor: three XPL2 ports, EchoServer class, dark debug console, qmllint clean

- Xpl2Client: replace single port with commandPort/imagingPort/statusPort (9110/9111/9112)
- Mock server: extract EchoServer class from lambda-based listenOn()
- Demo: dark debug console matching BobinkQtOpcUa style, 2-column connection layout
- Fix qmlls module resolution via IMPORT_PATH in qt_add_qml_module()
- Add pragma ComponentBehavior: Bound, fix all qmllint warnings
