Fix KBDPad MKI backlight, Num Lock LEDs; clean up firmware a bit (#6883)

* Update keyboard kit URL

* Replace custom RGB driver with new one from #7183

* Replace backlight with standard impl

* Remove some unnecessary default settings

* Disable COMMAND since docs want it off by default

(There's no working IS_COMMAND set for this board anyway, so it's
already a nop.)
