fix: add SyslogIdentifier to systemd services for proper journal logging

- Add SyslogIdentifier to aitbc-blockchain-p2p.service
- Add SyslogIdentifier to aitbc-agent-registry.service
- Add SyslogIdentifier to aitbc-ai.service
- Add SyslogIdentifier to aitbc-blockchain-sync.service
- Add SyslogIdentifier to aitbc-load-secrets.service
- Add SyslogIdentifier to aitbc-monitoring.service
- Add SyslogIdentifier to aitbc-openclaw.service
- Add SyslogIdentifier to aitbc-plugin.service

This ensures services log with their service name instead of 'python' or 'poetry' in journalctl.
