daemon: doctor passes vm dns when banger itself owns the port 
The previous check tried to bind 127.0.0.1:42069 and warned on
'address already in use' — which is exactly the state when the
banger daemon is running, the case the user ran 'doctor' to
confirm. The warning was actively misleading.

Now, on 'address already in use', probe the listener with a
*.vm DNS query that only banger's vmdns server answers
authoritatively (NXDOMAIN with Authoritative=true). If the shape
matches we pass; if the port is held by something else we still
warn. Tests cover both branches: a real vmdns server is accepted,
and a silent UDP listener on the same port is rejected.
