Add an error message when login fails because of domain misconfiguration

Browse Source 
Previously, we just output whatever err.responseText was. However, that
has some downsides:

- If there's no responseText (as for when we can't find the domain) then
  the user gets a blank message.
- If it's a 404 error, the responseText includes the full HTML for
  Puter's 404 page, which we don't want to dump in the error box! This
  is unlikely to happen in practice, but was easy enough to cater for.

So, add a nicer message in those cases.

The misconfiguration message is taken from here:
https://github.com/HeyPuter/puter/issues/185#issuecomment-2037977592

Resolves #235.
