feat: 实现 OpenAI token 自动刷新功能并优化账户管理界面

主要更改：
1. OpenAI Token 自动刷新
   - 实现 refreshAccessToken 函数，支持 OAuth 2.0 refresh_token grant type
   - 使用 Codex CLI 官方 CLIENT_ID (app_EMoamEEZ73f0CkXaXp7hrann)
   - 支持 SOCKS5 和 HTTP/HTTPS 代理
   - 自动更新 access token、id token 和 refresh token

2. 账户管理界面优化
   - 移除手动刷新 token 按钮（桌面端和移动端）
   - 保留后端自动刷新机制
   - 优化代码结构，删除不再需要的函数和变量

3. 测试和文档
   - 添加 test-openai-refresh.js 测试脚本
   - 创建详细的实现文档

技术细节：
- Token 端点: https://auth.openai.com/oauth/token
- 默认有效期: 1小时
- 加密存储: AES-256-CBC

所有平台现在都支持自动 token 刷新：
✅ Claude - OAuth 自动刷新
✅ Gemini - Google OAuth2 自动刷新
✅ OpenAI - OAuth 自动刷新（新实现）
