Fix: Ensure client_id parameter is always sent in query_server_last_sync request

- Make client_id parameter optional in query_server_last_sync()
- Auto-generate client_id if not provided using _get_client_id()
- Add debug logging for client_id parameter
- Fixes 400 error when server requires client_id parameter
