Improved external domain connection flow

The external domain connection flow now detects your current domain provider (like GoDaddy) and provides a direct login link, removing the need to search for the right page. The redesigned step-by-step layout makes the process feel more manageable, with connection method options now prominently visible instead of hidden. You can subscribe to email notifications when your domain is connected, which is especially useful for nameserver changes that can take up to 24 hours. For DNS-based connections, you'll see real-time confirmation as soon as changes are detected, and at the end of the flow you'll get a direct link to check nameserver propagation progress. The update also includes a new "Domain is Connecting" status that gives you 24-hour visibility into the connection process.
