Fix auth test: correct expected error message for unauthenticated org access

The test was expecting 'Unauthorized: Invalid organization access' but the
authorizeAnalytics function first checks if userId is null and throws
'Unauthorized: User required' before reaching the organization validation.

This fixes the failing test in CI by aligning the test expectation with
the actual function behavior.
