fix(cockpit): 补齐事件与边界 freshness

 - 第 7 轮补充 Redis GET/SET 运行时异常测试：适配器将缓存连接故障包装为 `CockpitReadException`，控制器契约映射为 `500 SERVER_ERROR`，不误报为 `SNAPSHOT_EXPIRED`；定向与全量回归均通过。
 - 第 8 轮本机受控性能烟测：同一真实 `snapshotAt` 连续认证请求 30 次，30/30 成功，平均 24.10ms、P95 30.60ms、最大 34.35ms；本次 live 数据样例 `total=7`。该结果仅代表本机进程和当前数据量，不替代生产规模压测。
 - 第 9 轮逐端点扫描：16 个主要 endpoint 全部 HTTP/app code 200；扫描到的全部 ISO 时间戳均为 `+08:00`。其中 11 个 endpoint 显式提供 freshness；`events/current`、`events/history-analysis`、`events/handling-efficiency`、`events/multidimensional-analysis` 和 `device-boundary` 当前没有统一 freshness 字段，仍是未完成契约项。
+- 第 10 轮为 `events/current`、`events/history-analysis`、`events/handling-efficiency`、`events/multidimensional-analysis` 和 `device-boundary` 响应 DTO 补充兼容 `freshness` getter：按已有事件/边界数据返回 `CURRENT` 或 `EMPTY`，不改变既有构造器；定向与全量回归均通过。
 - **验收边界**：上述 200/readOnly 证明当前本机实例的认证与响应契约，不等于 #63 全部切片的代表性真实数据、空/脏数据及故障场景均已验收。静态装配盘点显示 23 个 `Empty*Adapter` 均有对应的 `@Primary Business*Adapter`（另有 1 个共享事件事实适配器）；`Empty*Adapter` 作为 fallback 保留，不能仅凭类仍存在判断运行时未接线。目标部署实例仍需验收，issue 保持开启。
 - WebSocket `/ws/deviceStatus` 真实浏览器验收通过：发送 `cockpitSubscribe(scope=all)` 后收到 `cockpitSubscribed`，响应带 `serverUpdatedAt`；所有抽查时间戳为 `+08:00`。
 - 目标部署地址 `192.168.110.30:8301` TCP 不可达，因此没有把它当作本轮 HTTP 证据；生产部署实例、性能压测、银河麒麟与 Docker 实机验证仍未执行。
