feat(ux): U1 虚拟滚动 — Pod/事件/审计/命令列表大数据量渲染优化

- 安装 @tanstack/react-virtual@3.14.4
- 新增 hooks/useVirtualRows.ts 可复用虚拟滚动 Hook
- PodsTab: 全量渲染→虚拟滚动, 支持 1000+ Pod + 动态行高(展开行)
- EventTable: 移除 maxRows=200 截断, 万级事件流畅渲染
- AuditOperationsTab: shadcn Table→虚拟滚动 CSS Grid 布局
- SessionCommandsPanel: 虚拟滚动, page_size 200→500
- npm run build ✅, tsc --noEmit ✅, 17/17 集成测试通过

+**问题**: Pod 列表（1000+ Pod）、事件列表（maxRows=200 截断）、审计日志列表在大数据量场景下渲染卡顿
+
+**已完成 (2026-06-27)**:
+- ✅ 安装 `@tanstack/react-virtual@3.14.4`，新增 `hooks/useVirtualRows.ts` 可复用虚拟滚动 Hook
+- ✅ **PodsTab** (deployment-view): 从 `.map()` 全量渲染 → `useVirtualizer` + `measureElement` 动态行高，支持展开行，自动统计总数
+- ✅ **EventTable**: 移除 `maxRows=200` 截断限制 → 虚拟滚动渲染万级事件，CSS Grid 布局对齐表头
+- ✅ **AuditOperationsTab**: 从 shadcn `<Table>` 全量渲染 → 虚拟滚动 CSS Grid 布局，保留所有筛选/导出/详情功能
+- ✅ **SessionCommandsPanel**: 从 shadcn `<Table>` 全量渲染 → 虚拟滚动，page_size 从 200 提升至 500

+- [x] `@tanstack/react-virtual` 已安装并集成
+- [x] Pod 列表支持 1000+ Pod 虚拟滚动渲染（只渲染可见行 + overscan）
