feat: stage the wallpaper on homepage and notify on completion

bin/udt-homepage replaces install.sh's inline scp. It stages custom.css
and the current wallpaper, keeping the wallpaper's own extension, then
raises a desktop notification with the root commands that install both
and point settings.yaml at the new background. Plain root commands, not
sudo: the login user on that host has no sudo rights.

udt-accent starts it detached on every run, so it follows a wallpaper
change (wallp) as well as a scheme switch (install.sh) without holding
either up when the host is unreachable.
