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.
