refactor(miniprogram): 消灭全部 any 类型 — 32处 → 0 (E3-1)

- catch (err: any) → catch (err: unknown) + instanceof Error 类型缩窄（6 文件 13 处）
- BLE 回调类型提取 BLEScanResult/BLEConnectionChangeResult/BLECharacteristicChangeResult/BLEServiceItem
- BLEManager 7 处 any 注解替换为具体接口类型
- request.ts method as any → method as ValidMethod 字面量联合类型
- appointment ScheduleItem 接口定义替代 any[]
- Taro.requestSubscribeMessage 使用类型断言替代 as any
- globalThis.__hms 使用 Record<string, unknown>
- TrendChart Canvas/useRef 保留 eslint-disable（微信 API 限制）
- 0 TS 错误，119 测试通过
