Domains: No confirmation after domain-only purchase

[breezyskies]

Purchasing only a domain lands you here, with no confirmation the purchase went through.

The “xyz.live is not set up yet” which could be confusing in this context since you didn't get any feedback about the purchase.

Some options:

1. Add the green "thank you" notice after checkout, with a CTA to proceed to manage the domain (vs. "view site").
2. Add some confirmation text or notice on the current page the user lands on.

There is already an issue for adding some more copy on this screen, to explain the new domain delay: #11441

We can also improve the "not set up" copy in the title, which is not very useful. For example:

example.com: Temporary page

I like the idea of a dedicated confirmation screen like we do on NUX checkout to make it more obvious and reduce any confusion with the "not set up" information and sad-looking illustration being so prominent.

The copy looks good, but the button should probably say something like "go to your domain" or something. "manage domain" is already used in a different context.
