* docs(gateway): document Docker bridge networking and loopback bind caveat
The default loopback bind makes the gateway unreachable with Docker
bridge networking because port-forwarded traffic arrives on eth0, not
lo. Add a note in both the Dockerfile and the configuration reference
explaining the workarounds (--network host or bind: lan).
Fixes#27950
