feat: 添加飞书环境调试页面和详细日志

修改内容：
1. 新增 debug-feishu.tsx - 飞书环境调试页面
2. approval/detail.tsx - 添加详细的调试日志
3. router/index.tsx - 添加调试页面路由
4. business-trip.ts - 修复 import 错误

调试页面功能：
- 检测是否在飞书客户端内
- 显示 window.tt 等对象状态
- 测试飞书免登功能

使用方法：
1. 在飞书客户端中打开: https://xsm.dev.hnxinyouhe.com/debug-feishu
2. 查看环境信息
3. 点击"测试飞书免登"按钮
