Notes:

• Aims are now fetched from Opensearch instead of Contentful as discussed in previous standups
• In commit 714b0c0 ("removes redundant loggedInUser from opensearch search method"):
  loggedInUser was being passed all the way from the route → controller → data provider, but the auth check (if (!loggedInUser) throw Boom.forbidden()) already lives in opensearch.route.ts before the controller is ever called. The guard in the data provider was therefore unreachable in practice — any unauthenticated request would have been rejected at the route level first. Removing it from the data provider also unblocks internal server-side callers (like the project data provider) from using search without needing a user in scope.

In commit 714b0c0 ("removes redundant loggedInUser from opensearch search method"), loggedInUser was removed from most test assertions — but the "should handle empty request body" test case was missed. Its assertion still had expect.any(Object) as the third argument while all the other tests in the same file had that line removed.
