On the location's Mac that runs Companion, one line installs the panel from another location's settings

are picked, the gear is found (settings/discover.py) and turned into keys (settings/autoconf.py),
and that config is applied like any Apply on the page. Each other computer runs one join line
(Terminal on a Mac, an administrator PowerShell on a PC); from then on the settings page looks again
