/**
 * Memories (photo-providers) module e2e — exercises the migrated
 * /api/integrations/memories endpoints (unified + immich + synologyphotos)
 * through the real JwtAuthGuard against a temp SQLite db. The provider services
 * and canAccessUserPhoto are mocked; fail/success stay real so the envelope
 * shapes are produced by the actual helper code.
 *
 * Focus: auth (401), every route's happy path, the CRITICAL 200-on-failure
 * behaviour of /test + /status, and at least one error envelope per provider
 * router — all asserted byte-identical to the legacy Express routers.
