[Question]Monitoring and notification support differentiated association configuration

### Question

不同的监控能否支持配置不同的通知方式？
例：端口可用性监控，通知的方式可以任意选择已有的通知方式(飞书、邮件、短信等)中的一种或多种等
针对不同的监控通知不同的人群

The issue asks whether different monitors can use different notification methods and recipient groups, including port-availability monitoring. Start by clarifying the expected configuration scope and acceptance criteria; done requires a settled design for per-monitor notification associations rather than an unanswered question.
