    main: Activate notification proxy on start
    
    At least for the time being, this looks like the easiest option to
    launch the service:
    
     - we could add a systemd unit, but then we'd need to update the
       RequiredComponents in the fallback session definition as well,
       making it necessary for gnome-shell, gnome-shell-extensions and
       gnome-session to be updated to 3.36.1 in lockstep
    
     - autostart is problematic as it would make gnome-shell conflict
       with other notification daemons; also autostart is most useful
       with automatic shutdown, which would require tracking signal
       subscriber to determine when the service is unused
