+- `battery.batteries` returns paginated latest records per `mac`; supported filters are `pageSize`, `cursor`, `search`, `lowPower`, `powerStatus`, and `sort`.

 - Dashboard may call the external prediction API when `SOH_PREDICTION_API_BASE_URL` is configured. Prediction results are cached in memory by `mac` and latest history record.

 - `battery.dashboard`：读取每个 `mac` 的最新记录并生成看板聚合数据
