feat(activity): 弹窗食材/调料查询使用独立 StateFlow，新增调料列表双布局切换功能

- NetViewModel 新增 foodSearchGoodsListState 和 queryFoodSearchGoodsList，与 goodsListState 隔离
- FoodSearchDialog、SeasoningSelectDialog 改用弹窗专用 State，避免影响 FoodRecognizeActivity 列表
- SeasoningWeightAdapter 支持 Grid（4列）/List（2列）双布局模式
- SubmitFoodActivity 添加调料列表布局切换按钮
- FoodModule 变量重命名并添加未初始化保护
- 注释掉 mock 食材数据，调整相关布局边距与文字截断
