feat(03-02): Asset Service 接入 Gateway sync-info（DEVICE-04）

- Service 结构体新增 gatewayClient 字段，New() 追加 gatewayClient 参数
- Refresh device 分支在绑定卡刷新后调用 SyncDeviceInfo，nil guard + Warn 日志不阻断主流程
- 新增 updateDeviceFromSyncInfo 私有函数：更新 5 个 device 字段 + 调用 UpdateIsCurrentByDeviceID
- bootstrap/services.go asset.New() 调用追加 deps.GatewayClient
- go build ./... 零新增编译错误
