blockingCountingOAuthHandler is an OAuthHandler that blocks inside Authorize until the caller's context is cancelled, then returns a custom error that does NOT wrap context.Canceled. This mirrors real-world OAuth handlers that catch the cancellation internally and surface their own error type. The f

// relying on the error from Authorize, so this must still trigger c.fail().
// It records how many times Authorize is invoked.
