refactor(frontend): api/components/pages 目录架构统一对齐菜单域 + 日志中心修复

1. 目录架构统一（API = components = 菜单域，一域一目录 + barrel）
   - log/ 提为独立顶层域（日志中心在菜单中与监控中心平级，不再塞在 monitor/）
   - task/ 拆分原 automation.ts → cron-job / script / remote-exec
   - aiops/ 合并 ai.ts + agentCli.ts → assistant + agent-cli
   - agent/ approval/ audit/ 提升为域目录
   - auth 拆分：authApi(认证自服务) + system/user.ts(userApi+ldapApi 管理端)
   - components/automation → components/task，菜单"自动化运维"→"作业任务"
   - pages/ 按域分子目录(approval/audit/monitor)，删孤儿 AuditPage.tsx
   - 所有 API 符号名不变，组件经 @/api 聚合引用，运行时行为零变化

2. Loki 查询无返回修复：aiops 容器 DNS 解析外网域名失败
   （宿主机 systemd-resolved 转发链路异常），docker-compose 显式配 dns 上游

3. ES 查询框布局：工具栏单行挤 7 控件(ES 多 150px 索引框)，拆两行——
   查询输入独占一行(+查询按钮)，次级控件换行 flex-wrap
