Fix ProxyAwareTransport: set self.verbose before parse_response

Transport.parse_response() accesses self.verbose for debug logging but
it is never initialized unless the standard single_request() flow runs.
Our custom request() bypassed that, causing AttributeError on every call.
Fix: assign self.verbose = verbose before calling self.parse_response().
