Renders the swarm host (or "master") that a topology is deployed to, both as a meta line on each topology list card and in the war-map header. Operators can now distinguish master-local from agent-targeted topologies at a glance — previously the only signal was the abstract "mode: agent" label, with no hint of which agent. Adds useSwarmHosts() hook for the uuid → host lookup. Falls back to a short uuid prefix when the hosts list is unavailable so the UI never hard-fails on a missing /swarm/hosts response. TopologySummary gains target_host_uuid in the frontend type so the field actually narrows when checked.
