/**
 * Integration tests — GET /api/memory/engine-status
 * Tests: 200 + valid MemoryEngineStatusSchema shape, 401 unauth.
 *
 * NOTE: We use the real engineStatus() here (no mocking) because:
 * 1. engineStatus() is a named ESM export that cannot be redefined via mock.method
 * 2. engineStatus() returns a valid structure even with no providers/embeddings configured
