/**
 * Vacay module e2e — exercises the migrated /api/addons/vacay endpoints through
 * the real JwtAuthGuard against a temp SQLite db. DI-native: VacayService runs
 * its real SQL over the temp db (no legacy service mock); only the websocket
 * and notification side channels stay mocked. Focuses on auth, status codes
 * (POSTs stay 200), the Zod-pipe 400 envelope and a 403 body.
