A DANTE hold on missing hardware restarts Companion's Dante module.

Dante Virtual Soundcard on the four Macs is restarted directly; for hardware
(consoles, racks, cards, AVIOs) nothing can be restarted from here, so a hold
re-checks via a fresh Dante module connection (harmless to audio and routing).
If the device is still gone it is really off or unplugged. A check's fix can
now be "restart-connection", and a fix map can use "*" for every other sub-check.
