fix(network): derive the host IP from the default route, not hostname -I order

lfg2025/archy

On a fresh ISO node, NetBird's own WireGuard tunnel (10.44.0.1) sorted
ahead of the real NIC in hostname -I, so the NetBird launch URL (and the
{{HOST_IP}} baked into its cert/config) pointed at the tunnel instead of
the LAN address. The main routing table's default route names the
physical uplink even while a VPN is active (NetBird/Tailscale steer
traffic via policy-routing rules, not the main table), so read src/dev
from 'ip -4 route show default' first, then fall back to a connected UDP
socket's source address, then to the old hostname -I scan.
