任务完成后的 HTTPS 回调地址
回调时机：
- 任务完成（completed）或失败（failed）时触发
- 在计费确认完成后发送
安全限制：
- 仅支持 HTTPS 协议
- 禁止回调到内网 IP 地址（127.0.0.1、10.x.x.x、172.16-31.x.x、192.168.x.x 等）
- URL 长度不超过
2048字符
回调机制：
- 超时时间：
10秒 - 失败后最多重试
3次（分别在失败后1/2/4秒重试） - 回调响应体格式与任务查询接口返回格式一致
- 返回 2xx 状态码视为成功，其他状态码触发重试
示例:
"https://your-domain.com/webhooks/video-task-completed"
