## Problem
Favorite records (`NavigationMenuItems`) were not showing in the sidebar
under Favorites as the BE was returning `null` for
`targetRecordIdentifier`.
## Root cause
The `targetRecordIdentifier` resolver used `context.req`, which does not
have the typed `WorkspaceAuthContext` shape.
## Fix
Use `getWorkspaceAuthContext()` instead of `context.req` so the resolver
receives the typed auth context.
