feat: integrate actual blockchain mining with PoA consensus and fix CLI wallet operations

🔗 Mining Integration:
• Connect mining RPC endpoints to PoA proposer for real block production
• Initialize PoA proposer in app lifespan for mining integration
• Add mining status, start, stop, and stats endpoints with blockchain data
• Track actual block production rate and mining statistics
• Support 1-8 mining threads with proper validation

🔧 PoA Consensus Integration:
• Set global PoA proposer reference for mining operations
• Start
