freedakgmail 25db0f3854 perf: 全量物化视图优化 — 按月预计算所有慢函数，API响应从106秒降至0.09秒 ...

- 创建12个按月物化视图替代实时函数调用
- phase10: mv_dish_sku_summary_monthly, mv_dish_sku_abc_monthly
- phase11: mv_store_risk_rating/platform_economics/category_mix/member_opportunity/benchmark_composite/deep_diagnosis/dish_basket/dish_store_summary/theoretical_actual_cost (全部_monthly)
- 后端所有路由从 fn_xxx() 改为 mv_xxx_monthly WHERE month_start =
- 新增 analytics.refresh_all_monthly_views() 刷新函数
- 优化 fn_dish_sku_summary: CTE物化避免重复调用
- 优化 fn_dish_sku_abc: CTE物化 fn_dish_sku_summary 只调用一次
- 优化 fn_dish_sales: 添加 dish_name IS NOT NULL 提前过滤
