feat(dwl): autostart apps and pin them to tags via custom rules

fix: do not stop wlr services on logout

fix: stop wlr-services if running on dwl startup

When wlr-services services are running already from previous session,
ie. after a logout or a crash, they couldn't be started again, 1.
because wlr-services has been running still, it needs to be stopped
first, 2. because the services got disabled cause they crashed with no
possibility to connect to wayland display 5 times.

The point 1. is fixed by this commit, 2. is fixed in guix-exprs
