fix(management): drilldown生命周期历史改peer键控对齐批次A口径+comparisons键域统一+补测试

评审修正(I1/M1-M4/M6):
- I1 lifecycle_customers 历史改 (channel,peer) 键控跨owner合并,归属仍由
  Customer.owner_account_id 决定——与批次A _lifecycle_daily 同口径;新增
  共享客户测试(历史在他人账号下仍全量呈现)
- M3 employees 行 comparisons 键域统一为指标源名(config code→spec.metric
  映射,active_friends_band/call_band 不再出现),与 sections 一致
- M4 未回复分支空 owners 先短路,免去无效 finalize 调用
- M1 employee_metrics._percentile 改公有 percentile 供同包复用,删除
  api_assembly.percentile_nearest(存储层 _percentile 不同层保留)
- M2 drilldown 内联 SQL(FirstReplyFact/PhoneCall)下沉 api_assembly
  (fr_fact_rows/user_calls_page),路由层无裸查询
- M6 补 start>end→422 断言;新增 config_source=db 测试(激活配置
  min_days=9→五天数据员工翻 insufficient_sample,守护生效可见)
