Missing fields that the Qobuz server needs to register a renderer:
- device_uuid: persistent UUID (generated once, saved to disk)
- capabilities: min/max audio quality + volume_remote_control
- serial_number: null (same as desktop)
Without device_uuid, the server can't identify the renderer and
won't send SESSION_STATE.
Copied from desktop's default_qconnect_device_info_with_name.
