feat(config): add swarmctl-host to INI, env, CLI; drop hardcoded bind from systemd unit

Browse Source 
[swarm] swarmctl-host → DECNET_SWARMCTL_HOST so operators set the bind
address once in decnet.ini; `decnet swarmctl` and the systemd unit both
resolve it via envvar — no --host/--port pinned on ExecStart.
