[AI Generated]: feat(device): 扫描命中缓存设备自动连接（不跳转），整卡点击按状态跳转/连接

- connectedDevice：扫描列表与 connectDeviceInfo 缓存按 deviceId 实时比对，命中后一次性自动连，仅刷状态/缓存不跳页
- connectedDevice：新增 onTapCard，整卡点击 → 已连接跳 connectedWifi，未连接走 onConnect；按钮改 catch:tap 防冒泡
- connectedWifi：移除 onConfirm 中下发主用户与 calcAge/StoredUserInfo 残留，统一跳 supplementPersonal
