feat(diagrams): add findLatestContentHashForAppRoute with app-route cache

Browse Source 
Agent-scoped lookups miss diagrams from routes whose publishing agents
have been redeployed or removed. The new method resolves by
(applicationId, environment, routeId) + created_at DESC, independent of
the agent registry. An in-memory cache mirrors the existing hashCache
pattern, warm-loaded at startup via argMax.
