Allow using sudo when needed

[getzze]

Thanks for the great tool, it's very appreciated!

Currently (v0.4.0), when running systemctl-tui, I can see all the system services but when I want to start one, I get an error, Permission denied, of some sort. So I need to run it with sudo systemctl-tui. However I don't see my user services with sudo systemctl-tui.

I would like to be able to run systemctl-tui unprivileged, and be ask of the sudo password when I need to, to start/stop a service for instance.
paru does that for instance.

I agree, this would be a good feature.

sysz can be started without sudo, and when we needed actions like restart/disable, it will prompt for sudo password which is the better way, right now, we have to start systermctl-tui with sudo.
