fix(customers): 客户列表排序实时对齐云客(全局实时body刷新last_chat_time,前5位逐位一致)

- scrape_friends 双阶段:逐员工全量保底 + 全局实时body(friendTab=all/isOnJob/ymd窗)
  刷 last_chat_time(该参数集跨员工按最近沟通实时排序,实测比**赐14:10实时值)
- 阶段2只刷last_chat_time且只增不减(全局结果含旧ES副本,upsert全字段会被后写覆盖)
- 调度4h增量改为 friends→wa-friends→messages(排序键每4h实时化)
- 实测我们top5=云客top5逐位一致(A**杰14:13/比**赐14:10/P**6/A**邱/J**n)
