 * Real Manage Users CRUD through the admin UI (`admin.manage-users.spec.ts`
 * only opens/closes the panel — it never exercises create/edit/delete), plus
 * a causal cross-session check: an admin deactivating a user immediately
 * signs that user out of their *already open* session, because the NextAuth
 * `jwt` callback re-checks `isActive` from the DB on every request (see
 * `viewer-frontend/app/api/auth/[...nextauth]/route.ts`, issue #57 fix).
 *
 * punimtagdev shares its Postgres DB with MirrorMatch and reuses the same
 * pre-seeded accounts as other specs (E2E_ADMIN_EMAIL, E2E_VIEWER_EMAIL), so
 * every test here creates its own disposable `e2e-manage-test-*` account and
 * deletes it in a `finally`, regardless of outcome.
