New Hosts nav section: a fleet list (/hosts) + per-host detail (/hosts/{id}),
read-only (GET only, no host actions). Surfaces identity, agent version,
online/stale status (reusing the HostStalenessChecker threshold), guests,
vitals, storage targets with SMART/thin-pool, and DR/escrow presence.
- store: new ListGuestsForHost reader (reality cols only; omits api_key/
desired_spec_json) + scanGuest helper.
- web: handleHostsList + handleHostDetail (hosts.go); hosts.html +
host_detail.html; Hosts nav link on every page; timeAgoPtr helper; routes.
- tests: store getter, both handlers, no-secret (api_key) assertion, 404,
no-report empty state, status-band mapping.
