perf: Phase 12 — 物化剩余9个慢函数，全量API优化完成

新增物化视图:
- mv_store_action_priority_deep_monthly (10.7s→3ms)
- mv_inventory_cost_classified_monthly (37ms→3ms, 消除重复调用)
- mv_dish_pair_summary_monthly (171s→3ms)
- mv_store_area_efficiency_monthly (10.1s→3ms)
- mv_store_site_profile_monthly (9.3s→3ms)
- mv_site_segment_benchmark_monthly (12s→3ms)
- mv_store_site_replication_monthly (12.6s→3ms)
- mv_store_overlap_risk_monthly (88s→3ms)
- mv_district_site_benchmark_monthly (56s→3ms)

后端: 所有 fn_ 函数调用替换为物化视图查询
前端: BossPage 添加 MonthPicker 组件并传递 month 参数
修复: cost/category-benchmark 排序列名 store_code→sales_store_code
总计: 21个物化视图, 全部API响应<1.7秒
