母乳杯蓝牙改造：CAIIC-MCM 协议层(CLI/OTA)、设备/状态/升级页面、UI英文化、扫描不过滤、新应用名与图标

   version/sysinfo/bankinfo 显示、temp/fan（待固件）、本地 bin OTA 后 bankinfo 确认切 bank。
 - OTA 大数据量发送走 Write Without Response + 扇区级 ack 流控，若实测丢包导致
   status=2 重同步频繁，可在 OtaManager 扇区内加小窗口节流。

+## 后续调整（同日）
+
+- **uts 编译修复**：`match()` 结果元素可空需先判空；uts 函数不能直接当 lambda 传递
+  （改为箭头函数包装）；uvue 页面内函数需"定义在前、使用在后"；`setTimeout` 不接受
+  async 回调（改 then 链）；`java.io` 交互处需显式 `Int` 类型。
+- **UI 全面英文化**：pages.json 导航/ tab（Device/Status/OTA/my/CLI Terminal）、
+  home/sysStatus/ota/my/CLI 终端全部文案与 toast、OtaManager 升级日志消息、
+  manifest 应用名 `smartAssister`、iOS 蓝牙用途英文描述。
+- **扫描不过滤**：设备页去掉 `CAIIC-MCM` 名称前缀过滤，扫到的设备全部列出；
+  `BluetoothManager.startScan` 的 `showEmptyName` 改为 1（无广播名设备也返回，
+  列表中匿名设备显示 N/A）。
+- **APP 图标**：新增 `static/appIcon.png`（1024×1024，蓝色渐变底 + 白色母乳杯 +
+  蓝牙徽标，脚本生成），manifest 的 Android 四档与 iOS appstore 图标均指向它；
+  图标与应用名需重打自定义基座并重装后生效。
