SCA `RedirectUrl` rendering on 401 responses with no body

When the 401 error for SCA redirection (401 Unauthorized with the WWW-Authenticate: PendingUserAction RedirectUrl=... header) had no response body, RestTool reported the wrong outcome. connection.getErrorStream() returned null for the empty body, and the next line, checkApiConnection(is), threw a ResponseException with responseHttpCode=500 / responseHttpDescription="Connection to Mangopay API failed".

RestTool now better detects this case (responseCode == 401, error stream null, WWW-Authenticate header present) in both readResponse and doRequestList, and routes it through checkResponseCode(null, headers). The thrown ResponseException now carries:

responseHttpCode = 401 and responseHttpDescription = "SCA required"
data.RedirectUrl extracted from the WWW-Authenticate header
errors.Sca = "SCA required to perform this action."
type = "unauthorized"
