let user service depend on graphical-session
let user service depend on graphical-session

- use After to enforce starting only after DISPLAY is available
- use PartOf to stop service when graphical session is stopped (also see [systemd.special(7)](https://www.freedesktop.org/software/systemd/man/systemd.special.html#Special%20Passive%20User%20Units))
- make it installable so it can be enabled and started with the user session
- useful for dependent tools, like https://github.com/jle64/gnome-pass-search-provider
