feat(form): 实现餐品选择后自动加载食材功能

- 添加 NutFoodOptionVO 模型导入并增加 foodOptionsData 缓存列表
- 新增 ingredientsField 表单字段用于包含食材动态加载
- 将食材名称字段类型从 DROPDOWN 改为 FIXED 类型并移除固定选项
- 实现餐品选中后根据 position 从 compositions 加载包含食材逻辑
- 在 DictType 中新增 position 属性用于索引定位
- 在 FormField 中新增 onDropdownSelected 回调函数属性
- 更新 FormFieldAdapter 中触发选中回调并在日期字段注释中调整说明
- 修改 IngredientRowAdapter 中根据字段类型区分 FIXED 和其他类型处理
- 添加 extraApiKeys 到 extraValues 映射逻辑并更新下拉选中回调
- 调整 list_item_ingredient_row.xml 中食材名称布局去除右侧边距和下拉箭头
- 注释掉 NetViewModelV2 中的 getFoodOptions 方法（暂未使用）
