Module signer

Signer service module for handling cryptographic operations across different blockchain networks.

This module provides:

• Common signer traits for different blockchain networks
• Network-specific signer implementations (EVM, Solana, Stellar)
• Factory methods for creating signers
• Error handling for signing operations
