ALARMS and AUTO-FIX as two keys; LIGHTS at Southcoast hands the lights to an operator

- kind autofix: its own switch on the auto-fix hours; ALARMS then only silences (NA keeps the old
  combined key until it has room for one)
- kind bypass: hold takes every network MIDI link to a peer out (here and on listed Macs), checks stop
  calling it lost, re-taken every 10 s; hold again puts back exactly what was taken plus every watched link
- a MIDI peer with no address is never called (it connected SC Tracks to itself)
- holds from NA's CAMPUS page flip switch keys; a rebuild keeps them; new campuses get AUTO-FIX
- key kind changes restart the watchdog; settings page has separate alarm / auto-fix buttons
- WS and SC configs: AUTO-FIX at 3,1; SC LIGHTS at 1,3; NA config synced from live
