Clarify Admin URL in Custom Domain Settings

Currently, when you set up a custom domain, like subdomain.domain.com, accessible to both admins and clients, you can navigate to Settings -> Domain. However, the admin URL is always at /admin, which might not be immediately clear.

Solution:

We'll make it simple. After the subdomain, we'll add a link: ({domain}/admin). So, for example, if your domain is subdomain.domain.com, the admin URL will be subdomain.domain.com/admin.
