feat: upgrade to production-grade systemd services

✅ Production SystemD Services Upgrade
- Upgraded existing services instead of creating new ones
- Added production-grade configuration with resource limits
- Implemented real database persistence and logging
- Added production monitoring and health checks

✅ Upgraded Services
- aitbc-blockchain-node.service: Production blockchain with persistence
- aitbc-marketplace.service: Production marketplace with real data
- aitbc-gpu.service: Production GPU marketplace
- aitbc-production-monitor.service: Production monitoring

✅ Production Features
- Real database persistence (JSON files in /opt/aitbc/production/data/)
- Production logging to /opt/aitbc/production/logs/
- Resource limits (memory, CPU, file handles)
- Security hardening (NoNewPrivileges, ProtectSystem)
- Automatic restart and recovery
- Multi-node deployment (aitbc + aitbc1)

✅ Service Endpoints
- aitbc (localhost): Marketplace (8002), GPU Marketplace (8003)
- aitbc1 (remote): Marketplace (8004), GPU Marketplace (8005)

✅ Monitoring
- SystemD journal integration
- Production logs and metrics
- Health check endpoints
- Resource utilization monitoring

🚀 AITBC now running production-grade systemd services!
Real persistence, monitoring, and multi-node deployment operational.
