* fix:(default-flatpaks): Missing notification for system flatpaks
This approach, while more fragmented, it's cleaner, as there is a clearer separation of root & non-root operations done by flatpak-setup service. This should probably increase security too (but I'm not the expert to talk seriously about that). It also gets rid of some non-harming error for /var data, can't remember it fully.
While it may be confusing for users that they have to type:
`systemctl status --user system-flatpak-setup`
instead of previous:
`systemctl status system-flatpak-setup`
It is something worth sacrificing for the important user-experience fix.
