feat: merge persistent route catalog into unified catalog endpoint

Wires RouteCatalogStore into CatalogController as a third data source:
routes with zero executions and routes from previous app versions
(within the queried time window) now appear in the unified catalog.
Also clears route_catalog on app dismiss via deleteByApplication().
