Add smart service start with automatic log exit

- Service start now follows logs in real-time until service becomes active
- Automatically stops log following when systemctl reports service as active
- Eliminates need for manual Ctrl+C to exit log stream
- Shows final service status after startup completes
- Background monitoring loop checks service state every second
