Marcos Miller 5e27373700 network: Show top buttons on unsupported network daemon page 
When entering the network panel without the network daemon,
the window decoration buttons do not appear because the whole panel
content was overwritten by an AdwStatusPage.

Now only the content of the AdwToolbarView is changed, preserving
the AdwHeaderBar and buttons.

Fixes https://gitlab.gnome.org/GNOME/gnome-control-center/-/issues/2695
