Clear ID_INPUT_JOYSTICK on the Keychron keyboard (3434) and X3PRO mouse receiver (3151) so Steam/games stop grabbing them as a phantom controller. Also grant the active session uaccess to those devices' hidraw nodes via a 60-*.rules package file (must sort before systemd's 73-seat-late.rules) so their browser-based WebHID configurators work.
