Fix: Only send client_id parameter when rustdesk_id is configured

- Check if rustdesk_id is configured before sending client_id parameter
- Use rustdesk_id value as client_id when configured
- Do not send client_id parameter if rustdesk_id is not set
- Fixes 400 error when server requires client_id only when configured
