Ntfy listener: only run when the paired gateway pushes via ntfy — the foreground service (and its permanent 'Listening for messages' notification) is now started/stopped based on the gateway's push backend from hello.ack server_caps (persisted as pushBackend); FCM gateways no longer keep a persistent listener alive, and switching gateways toggles the service on the next connect
