treewide: use graphical-session.target for GUI services
As per systemd.special(7)[0] graphical-session-pre.target is strictly
for units that set up things for a graphical session. Most notably,
these are usually started *before* the compositor/session is actually
ready.

While Home Manager's current implementation of graphical-session.target
allows these units to work regardless of what systemd.special(7)
specifies, other setups like ones with uwsm[1] do not allow these units
to start properly.
