Update tailscale_serve for qemu2 API server address

The k8s API server is now at 192.168.105.2:6443 (inside qemu2 VM)
instead of localhost:44491 (old podman port mapping).

Note: TCP passthrough via tailscale svc:k8s is configured but
connection times out - may need admin console approval or debugging.
