refactor(dunst): drop dunst as a consumer, quickshell presents now

dunst no longer runs on this desktop. notifyd owns
org.freedesktop.Notifications and the quickshell notifications shell
draws the balloons, reading the palette from ~/.cache/wal/udt-palette.qml
like every other quickshell component. So the whole dunst path was
generating a config nothing read.

It was also actively wrong. pywal rendered ~/.cache/wal/dunstrc from the
installed template, then wal.sh restarted dunst on it while @ACCENT@ was
still an unsubstituted placeholder, and udt-accent restarted it a second
time after substituting. Two restarts per wallpaper change, the first on
a broken config, for a daemon that could not claim the bus name anyway.

Removes gen_dunst and its TARGETS entry, write_dunst and DUNSTRC, the
install block, templates/dunstrc.in and the gitignore entry. The reload
table now lists quickshell, which needs no signal: it watches the
generated palette and re-reads it in place.

The [state] roles stay. They were never dunst-only; waybar module states
and conky warnings use the same four.
