DNS Working

Finally smoothed out the setup, config, and order of operations.

The DNS manager will bootstrap Core DNS and internal.jerkytreats.dev zone, look for Tailscale devices and add them to the zone.

I'll need to update the add-record endpoint to define which device to add the record to, but that should be straight forward.

I also had to update the NAS ipset to allow tailscale devices to connect to the DNS manager over port 53.

With that done, the internal DNS manager is working.
