feat(keyboard): light the AK820 Pro in the wallpaper accentHEADmaster

udt-keyboard sets an Ajazz AK820 Pro to its "launch" effect in the
current accent through ak820-ctl, and does nothing without it.
udt-accent starts it detached on every run; --watch reapplies the
accent when the USB cable is plugged in, since the keyboard takes no
commands over its dongle or Bluetooth.

The firmware ignores a mode change unless the lights go off first and
settle, so it sends off, waits three seconds, then the mode. A lock
keeps a wallpaper change and a plug-in from interleaving the pairs.
