A full monitor reload tears the state down and rebuilds it empty, so
agent-reported host rows vanish until each agent's next report lands.
Config fetches in that window 404ed with a perfectly valid token, which
showed up as rare correlated agent_config_fetch failures across
unrelated agents (#1570).
When the live snapshot has no match, resolve the host from the
persisted continuity store with the same semantics as the live path. A
report-scoped token resolves only its bound host and manage-scoped
tokens resolve by host ID. Deliberately removed hosts stay 404 because
removal deletes their continuity entry.
