refactor(main): 将Thread替换为lifecycleScope并优化协程处理

- 替换CollectFragment中的Thread为activity.lifecycleScope.launch
- 在MainActivity中添加FaceServer相关依赖和协程调度器
- 修改环境切换对话框以支持人脸数据重置功能
- 将照片拍摄和食物向量保存操作从Thread迁移到lifecycleScope
- 优化人脸识别数据更新逻辑，移除不必要的线程创建
- 修改onTakePhotoSuccess方法为suspend函数并调整UI更新方式
- 更新主线程操作使用withContext(Dispatchers.Main)替代runOnUiThread
- 在MainScreenPresentation中添加相机暂停功能
- 修复SensorScaleUtils中标定调用问题
- 扩展UserViewModel的人脸数据获取接口，支持回调处理
