feat: 全新的Vue3管理后台(admin-spa)和路由重构

🎨 新增功能：
- 使用Vue3 + Vite构建的全新管理后台界面
- 支持Tab切换的API统计页面（统计查询/使用教程）
- 优雅的胶囊式Tab切换设计
- 同步了PR #106的会话窗口管理功能
- 完整的响应式设计和骨架屏加载状态

🔧 路由调整：
- 新版管理后台部署在 /admin-next/ 路径
- 将根路径 / 重定向到 /admin-next/api-stats
- 将 /web 页面路由重定向到新版，保留 /web/auth/* 认证路由
- 将 /apiStats 页面路由重定向到新版，保留API端点

🗑️ 清理工作：
- 删除旧版 web/admin/ 静态文件
- 删除旧版 web/apiStats/ 静态文件
- 清理相关的文件服务代码

🐛 修复问题：
- 修复重定向循环问题
- 修复环境变量配置
- 修复路由404错误
- 优化构建配置

🚀 生成方式：使用 Claude Code
