refactor(quality): Q38 UnifiedQueryPanel 529L→353L (-33%) — 提取 useLogQueryEngine + useLogExport 自定义 Hooks，全项目最后一个 ≥500L 业务组件清零

- useLogQueryEngine.ts (295L): 查询执行引擎 Hook — 封装 loading/entries/statTable/clusters/histogramData/totalCount/queryTime/hasMore/liveTail/hasQueried 状态 + handleRun/handleLoadMore/fetchHistogram/runLiveTailTick + Live Tail useEffect(3s)
- useLogExport.ts (62L): 导出/复制 Hook — formatEntryLine + handleExportLogs(Blob) + handleCopyLogs(clipboard)
- 主文件保留: 数据源加载/URL bootstrap+sync/Loki 标签名/ES mapping effects + 派生数据 + 非查询回调 + JSX 子组件编排
- 首次使用 custom Hook 提取模式进行组件拆分
- tsc -b=0, npm build✓ (16.69s), ESLint=0/66/0, go build=0, 17/17 测试通过
