Change Asterix.Resolve() to use Tailscale's CGNAT range (100.64.0.0/10)
and ULA range (fd7a:115c:a1e0::/48) instead of all IPs (0.0.0.0/0 and
::/0).
This better matches Tailscale's security model where wildcard (*) means
"any node in the tailnet" rather than literally "any IP address on the
internet".
