refactor(utils): 重构 FoodVectorTool 并优化 zero() 提示控制

- 重构 FoodVectorTool：移除单例 pageNum 状态污染问题，分页逻辑下沉为私有 fetchPage，saveFoodVector 改为私有，PAGE_SIZE 移入内部定义，对外统一暴露 loadAndSaveFoodVector 接口
- 更新 InitActivity、MainActivity 调用方，移除重复的 onPageFinish 回调
- SensorScaleUtils.zero() 新增 isShowToastRemind 可选参数，支持按需显示标定成功提示
