feat: 添加飞书 JSBridge SDK 支持

问题：
- 移动端飞书 WebView 中 tt 对象没有被注入
- 导致免登功能无法使用

修复：
1. index.html - 引入飞书 H5 JSBridge SDK
2. approval/detail.tsx - 添加对多种飞书 API 的支持
3. debug-feishu.tsx - 更新调试页面，检测所有可能的 API 对象

支持的飞书 API：
- window.tt (标准 H5 应用)
- window.h5sdk (JSBridge)
- window.bridge (JSBridge)
- window.ttjsBridge (旧版)
