fix(waybar): call the bar's installer instead of copying one file

The palette reaches the bar as three generated files, not one: the stylesheet,
dots.colors for the two dot scripts, which are bash and cannot read
@define-color, and two tints of the Slackware mark, which has to contrast with
the accent pill at rest and the dark pill on hover.

Copying only the stylesheet meant a scheme switch recoloured every pill and
left the dots and the mark on the previous scheme. Generating the other two
here would have put a second writer on files the bar's own install.sh already
writes, drifting apart the moment either side was edited. So this calls that
script rather than reimplementing it, with UDT_PALETTE_DONE=1 so it skips the
palette run this one has just done.

Never fatal, like udt-appthemes: a failure there warns and leaves the bar on
its old colours rather than stopping kitty, Kvantum and Sublime from being
themed.

Verified by switching tokyo-night to nord and back with only this script: the
accent, DOT_SUCCESS and both mark tints followed in each direction.
