Add real-time validation for emails/screennames taken on IA to prevent random digit appending

[seabelis]

Patron reports that their chosen username was appended with numbers. The patron was not informed that this would happen during registration and understood the chosen username was available.

Evidence / Screenshot (if possible)

Relevant url?

Steps to Reproduce

According to @mekarpeles , this happens when the archive.org ID they request is available but the open Library ID is not.

• Actual: No warning that the chosen username is not available and will be appended
• Expected: If chosen username is not available warn the patron and give the opportunity to choose a different name.

Details

• Logged in (Y/N)?

Hi @seabelis, I'd like to help solve this issue if it's still open. Please guide. Thanks!

Perhaps @mekarpeles can provide some guidance on this?

@happycoding47 if you'd like to take a look at the code in openlibrary/account/model.py you should be able to see where this logic is being done within the audit function. See if you can propose a better way of doing this!
