(fix): improve status handling in API Domain

Properly handle cases where a non-200 status code is returned and the status text is in the response body - otherwise basically any error would end up in the body as a string (thanks, http/2) and result in an unmarshalling error.

Changes:
- added a "status" field, which is populated with the http.Status if included in the response, or the text from the http.StatusCode if not.
- don't error on a 404 (I swear I did that already, so I guess I did it for reals this time)
- don't try to unmarshal the body into a json object if the return isn't a 2XX

I'm sure I'm missing more edge cases, and welcome any suggestions, but hopefully this is better!
