Find Dante PoE devices by MAC automatically instead of hard-coding ports.

Browse Source 
Every 10 minutes the watchdog maps each Dante device: name and IP from
Companion, MAC from NA Ingest's ARP table, switch port and PoE state from
the Netgear switches in dante_switches, saved to dante-map.json. A DANTE hold
on a missing PoE-powered device power-cycles the port it is on now (found
live by MAC, or its last known port if it has aged out and nothing else is
there); never a port with more than 2 devices. Re-patching, adding or
renaming devices needs no config change. First live map: 19 devices, the 4
Studio B boxes on PoE.

**The Dante map is automatic.** Every 10 minutes the watchdog maps each Dante device: its name and IP from Companion, its MAC from NA Ingest's Dante port, and its switch port and PoE from the Netgear switches listed in `"dante_switches"`. It saves the map to `dante-map.json` in its data folder. Re-patching, adding or renaming a device needs no config change. A device that has been dead for a while ages out of the switch tables, so its last known port is used, but only if no other device has appeared there. A port carrying more than 2 devices (an uplink) is never power-cycled. The switch login is in NA Ingest's login keychain (service `netgear-status-panel`).
