I am also not aware of a "built-in" reboot/shutdown function and also
wanted to implement such function handling the switch to initiate a proper

We implemented a php-over-webserver function which mainly is a system
call to "sudo reboot" (and adding www-data to sudoers with
the NOPASSWD option)... works fine so far.
