refactor: 清理站内导航死代码 (删除孤立NavigationPage组件+navigationApi+导航mock数据)

- 删除 frontend/src/components/navigation/NavigationPage.tsx (359行, 菜单/路由移除后遗留的孤立组件)
- 移除 services/api.ts 中 navigationApi (唯一消费者已删除)
- 移除 mocks/modules/misc.ts 中 navigationGroups/navigationLinks 死数据 (252行)
- 清理 mocks/data.ts barrel 中导航 re-export
- 修正 cloud.ts 误导性注释 (站内导航→云平台/账号/区域/域名数据)
- 后端 navigation.go 保留不动 (菜单已移除但后端代码保留)
- tsc --noEmit 零错误 + npm run build 通过

frontend/src/components/navigation/NavigationPage.tsx
