perf: 并行化 admin 聚合路由并完善前端缓存预取

- gateway: usage detail / provider summary / pool overview / users list 改为 tokio join 并行拉取依赖数据
- usage: interval timeline 支持自动刷新并按查询区间动态展示，取消服务端 120 分钟过滤并在 ScatterChart 统一封顶
- frontend: 新增管理端导航预取工具及 SidebarNav/MainLayout 触发，admin 读接口统一走 cachedRequest 的短期缓存
- dashboard: request detail 支持短 TTL 缓存并在 UsageRecordsTable mousedown 时预取
- data: migrate 测试在 wait_for_postgres 失败时清理子进程，避免遗留
