feat(portal-shell): v2.0 P0 shadcn standardization + security + streaming + error handling

- shadcn/ui 标准化：废弃纸感令牌，统一 bg-background/text-foreground 等
- Tailwind v4 + @theme inline，移除 tailwind.config.js
- React 19 use() + Suspense 流式渲染，首屏骨架秒出
- 三级错误边界：Route → Section → Widget 层层兜底
- 错误上报：useErrorReport → sendBeacon → /api/log mock 端点
- 三层安全边界：L1 角色门禁 / L2 权限点门禁 / L3 数据范围
- 权限位图 base36 压缩：67 权限点 → ~14 字符，JWT 体积减少 ≥ 99%
- notify 统一 Toast 封装，禁止业务直接 import sonner
- PluginBoundary 替代 PluginLoader（错误边界 + Suspense + Skeleton 三件套）

验证：typecheck 0 错误 / lint 0 错误 / build 6 路由生成成功
