install: one function per consumer, runnable aloneHEADmaster

install.sh was one linear script, so the only way to re-theme kitty after
it drifted was to reinstall everything. Each consumer is now a c_<name>
function: `./install.sh kitty gtk` runs only those, no argument runs all of
them in definition order, and `--list` prints name, software|hardware and
what it themes, read off the function lines themselves. quickshell's Theme
status page lists and re-applies consumers through those two calls, so a
new consumer is a new function and nothing else.

udt-accent now runs before the consumers with a new --no-helpers flag.
Before it, every install ran it last and it started homepage, GRUB,
keyboard, LED strip, bulbs and TV detached, so re-applying conky also
repainted the strip. Those helpers are consumers of their own here, run in
the foreground so a re-apply reports how it went; wallp still starts them
all on a wallpaper change. Running the accent first means c_sublime fills
the template's @ACCENT@ itself, from udt-accent.rasi.
