Support for viewing the file contents of units, services, timers etc.

When I have a service which does not start properly it often helps me to look at its .service file to see how it is defined. A view or tab for this would be helpful.

Yeah that's a good idea. Right now systemctl-tui can copy the unit file path to the clipboard to help with that, but it might be nice to be able to toggle between logs and the unit file.
