Fix: Only include client_id in report data when rustdesk_id is configured

- Check if rustdesk_id is configured before including client_id in report data
- Use rustdesk_id value as client_id when configured
- Set client_id to None if rustdesk_id is not set
- Prevents sending machine-generated client_id when rustdesk_id is not configured
