feat: integrate Haskell DMQ network

[jpraynaud]

Content

This PR includes the integration of the Haskell DMQ node with the Mithril nodes:

• Created a DmqNetwork to represent the DMQ network (instead of using the CardanoNetwork)
• Implemented modifications in the structure of the DmqMsg
• Adapted the devnet to support an attached DMQ network
• Adapted the e2e test to support testing against the Haskell DMQ node

Pull Request Overview

This PR integrates Haskell DMQ (Distributed Message Queue) network support with Mithril nodes, enabling communication through DMQ in addition to existing methods. The changes introduce a dedicated DmqNetwork type to handle DMQ-specific networking while maintaining separation from the existing CardanoNetwork infrastructure.

Key changes include:

• Created new DmqNetwork model with separate magic IDs for DMQ communication
• Updated configuration to support both Cardano and DMQ network magic numbers
• Modified devnet infrastructure to support running DMQ nodes alongside Cardano nodes
