feat: OAuth Token 自动刷新调度、OAuth 对话框优化及 OpenAI CLI normalizer 重构

- 系统设置新增 OAuth Token 自动刷新任务开关，支持动态调度
- OAuth 授权对话框简化步骤布局，移除编号圆圈样式
- 重构 OpenAI CLI normalizer：将 if-else 链替换为事件处理器映射表，
  将 stream_event_from_internal 拆分为独立方法
- 维护调度器在禁用刷新时移除已调度的 job
- .gitignore 新增 CLIProxyAPI/ 和 sub2api/ 排除项
- 补充 noop/unknown 事件处理器的测试覆盖
