feat: add rate limit recovery webhook notifications

添加限流恢复的 webhook 通知功能，当账户从限流状态自动恢复时发送通知。

主要改进:

1. **新增通知类型** (webhookConfigService.js)
   - 添加 `rateLimitRecovery` 通知类型
   - 在配置获取和保存时自动合并默认通知类型
   - 确保新增的通知类型有默认值

2. **增强限流清理服务** (rateLimitCleanupService.js)
   - 改进自动停止账户的检测逻辑
   - 在 `finally` 块中确保 `clearedAccounts` 列表被重置，避免重复通知
   - 对自动停止的账户显式调用 `removeAccountRateLimit`
   - 为 Claude 和 Claude Console 账户添加 `autoStopped` 和 `needsAutoStopRecovery` 检测

3. **改进 Claude Console 限流移除** (claudeConsoleAccountService.js)
   - 检测并恢复因自动停止而禁用调度的账户
   - 清理过期的 `rateLimitAutoStopped` 标志
   - 增加详细的日志记录

4. **前端 UI 支持** (SettingsView.vue)
   - 在 Webhook 设置中添加"限流恢复"通知类型选项
   - 更新默认通知类型配置
