feat: 新增 OpenAI-Responses 账户管理功能和独立自动停止标记机制

## 功能新增
- 实现 OpenAI-Responses 账户服务（openaiResponsesAccountService.js）
  - 支持使用账户内置 API Key 进行请求转发
  - 实现每日额度管理和重置机制
  - 支持代理配置和优先级设置
- 实现 OpenAI-Responses 中继服务（openaiResponsesRelayService.js）
  - 处理请求转发和响应流处理
  - 自动记录使用统计信息
  - 支持流式和非流式响应
- 新增管理界面的 OpenAI-Responses 账户管理功能
  - 完整的 CRUD 操作支持
  - 实时额度监控和状态管理
  - 支持手动重置限流和每日额度

## 架构改进
- 引入独立的自动停止标记机制，区分不同原因的自动停止
  - rateLimitAutoStopped: 限流自动停止
  - fiveHourAutoStopped: 5小时限制自动停止
  - tempErrorAutoStopped: 临时错误自动停止
  - quotaAutoStopped: 额度耗尽自动停止
- 修复手动修改调度状态时自动恢复的问题
- 统一清理逻辑，防止状态冲突

## 其他优化
- getAccountUsageStats 支持不同账户类型参数
- 统一调度器支持 OpenAI-Responses 账户类型
- WebHook 通知增强，支持新账户类型的事件
