30-traefik.sh enabled traefik whenever the adopted net.traefik was true, even
on an IPv6-only box (net.v4_forward false). The domain proxy is only served
while BOTH v4 ingress and net.traefik are on, so traefik must stay installed
but DISABLED (no start, no boot autostart) when v4 forwarding is off, regardless
of the kept net.traefik value; re-enabling v4 later restores it. The start
branch is now gated on VPSMGR_V4_FORWARD first, matching the panel's own
ApplyTraefikState (V4Forward && Traefik).
