 * UI / OpenAPI document paths must NOT be anonymously reachable. They fall under
 * an explicit {@code hasRole('ADMIN')} rule in {@link SecurityConfig}, so an
 * unauthenticated request is rejected by the authentication entry point (401)
 * instead of leaking the full API surface.
 *
 * <p>Uses a real embedded servlet container ({@code RANDOM_PORT}) because the app
 * registers a WebSocket endpoint that requires a servlet {@code ServerContainer},
 * which the MockMvc-only environment does not provide.
