"""Notifications integration fixtures.

The app's DB session and auth-context dependencies are overridden to ride the
test's transactional `db_session`, so API calls and seeded rows share one
transaction that rolls back per test. Overriding `get_auth_context` also bypasses
real JWT auth, so these tests don't depend on AUTH_TYPE.
