feat(activity): 新增菜品识别功能，重构FoodRecognizeDialog并临时跳过调料配置检查
- 新增 FoodRecognizeDialog（继承 BottomSheetDialog），只初始化一次，暴露 loadData() 方法 - 新增 dialog_food_recognize.xml 布局（标题 + 2列 GridLayoutManager RecyclerView） - PrepareCookActivity 集成相机初始化、拍照识别流程（重量稳定 ≥10g 时触发） - PrepareCookActivity 新增 flCameraContainer（1dp 隐藏容器）用于相机预览绑定 - SelectDishActivity 临时注释 judgeDeviceConfig 逻辑，直接调用 block() - 修正 GpioUtils/L/LightManager 包名为 com.shuwei.dish.match.utils
