fix: P2/P3审计问题修复 + 更新审计文档移除已修复问题

- 修复schema前缀：确认central_kitchen/mv_distribution/mv_dish_sales等表在public schema，撤销错误的analytics.前缀
- 移除API内部物化视图刷新：mv_distribution_monthly/mv_dish_sales_monthly改为console.warn
- 修复BOM树节点key：使用path字段替代material_code+level确保唯一性
- 修复HR人才矩阵potential_score：基于v3_learning_record动态计算替代硬编码60
- 修复StoreDetailPage公司均值：优先使用API返回的companyAvg
- 修复前端字段名匹配：discount_rate_pct/check_comment等
- 添加explicit column list和LIMIT到大型查询
- 更新数据溯源审计.md：移除全部52个已修复/确认无需修复的问题条目
