/**
 * System-notices module e2e — exercises the migrated /api/system-notices
 * endpoints through the real JwtAuthGuard against a temp SQLite db. Focuses on
 * routing, auth, status codes and bodies, per its original scope.
 *
 * Plan 3f Task 6: `getActiveNoticesFor`/`dismissNotice` (formerly a separately
 * mockable plain module, `../../src/systemNotices/service.ts`) are now private
 * methods absorbed into `SystemNoticesService` itself, so there is no longer a
 * seam below the Nest provider to mock — `SystemNoticesService` is overridden
 * as a whole via Nest's `overrideProvider`, the same boundary
 * `system-notices.controller.test.ts` already mocks at. The release-layout
 * gating this test used to exercise through that lower seam (with a real
 * `SystemNoticesService` calling a mocked `getActiveNoticesFor`) is proven
 * directly against the real class in `system-notices.service.test.ts` instead,
 * now that the gating logic and the notice list it filters live in the one
 * class this file would otherwise have to fully re-implement to keep testing
 * through HTTP.
