Because it is sometimes never used.

I changed it to a separate condition rather than depending on the order of the case-when statements to prevent this mistake again.

And refactor to self-document a little better.

No external behavior change.

This allows `GitHttpController` to set the HTTP status based on the type of error. Alternatively, we could have added an attribute to GitAccessStatus, but this pattern seemed appropriate.

This already works due to previous refactoring.

Changes to `GitHttpClientController`’s authentication logic caused this behavior change.

The old 401 Unauthorized statuses didn’t cause any harm, but they weren’t quite as accurate as the new behavior.
