fix: don't show a bogus container IP for the network address under Docker

/api/network reported the container's bridge IP (172.x) when running in
Docker, which surfaced as a broken/"Error" value in Settings → About &
updates. Skip container-internal interfaces (detected via /.dockerenv) so the
endpoint returns no address inside a container, and guard the panel against an
unexpected response shape — both paths fall back to the helpful
"open via the server's IP" hint.
