Pull Request Overview

This PR replaces external IP address discovery with supernode address resolution from the Lumera blockchain. The change eliminates external HTTP calls to IP discovery services and instead queries the chain to get the latest registered address for each supernode.

• Removes external IP discovery utilities and HTTP-based address resolution
• Adds new GetSupernodeWithLatestAddress method to retrieve processed supernode information including latest address and state
• Updates P2P networking layer to use blockchain-registered addresses instead of external IP services
