[RaidenE1]

In the create topic request we send a CreateTopic request in an
Envelope, so we need to also unpack the response correctly

Pull Request Overview

This PR modifies the AutoTopicCreationManager to properly handle envelope responses for CreateTopics requests. When sending CreateTopics requests through envelopes, the responses need to be unwrapped from the EnvelopeResponse wrapper to access the actual CreateTopicsResponse data.

• Adds envelope response handling to both sendCreateTopicRequest and createStreamsInternalTopics methods
• Implements proper error handling for envelope-level errors and parsing failures
• Adds comprehensive test coverage for various envelope response scenarios
