It is recommended to merge SSL certificate monitoring with HTTP API/Site MAP

### Description

我们在做HTTP API、SiteMAP、网站监测等事项的时候，会手动勾选“启用HTTPS”，这个时候就默认监控ssl证书即可，不必单独一个创建一例ssl证书监控。节约资源

### Task List

_No response_

Review the existing SSL certificate monitoring and HTTP API/Site MAP flows, focusing on how the HTTPS option is handled. Define how enabling HTTPS should trigger certificate monitoring without a separate monitor, and verify that the merged workflow monitors certificates while reducing duplicate resource use.
