refactor: remove production naming from AITBC services

✅ Production Naming Cleanup Complete
- Renamed aitbc-production-monitor.service to aitbc-monitor.service
- Removed production suffix from all SyslogIdentifiers
- Updated log paths from /var/log/aitbc/production/ to /var/log/aitbc/
- Fixed service configurations and syntax issues
- Created dedicated monitor script for better maintainability

✅ Services Standardized
- aitbc-monitor.service (clean naming)
- aitbc-gpu.service (no production suffix)
- aitbc-blockchain-node.service (no production suffix)
- aitbc-agent-coordinator.service (no production suffix)
- All other AITBC services updated

✅ Environment Simplification
- Single environment: staging runs over git branches
- No production naming needed (only one environment)
- Clean service naming convention across all services
- Unified log directory structure under /var/log/aitbc/

🚀 Production naming issues completely resolved!
