Improve handling of httperrors.Error

The backend should handle errors as the error type if possible. With the current approach, a lot of code is duplicated.
See https://go.dev/doc/faq#nil_error for details.
However, we also want to transport the HTTP status code. This needs some more thinking and research.
It might be possible to have a generic handler function for the errors that takes the Response type as parameter via a suitable interface and can then return the correct response. With that, the handling code could possibly be much shorter.

We can't use the error type in response structs since an error marshals to {}, see golang/go#5161.
