An item cannot be prepared or completed

The item may already have changed on another device.

1. Refresh the POS order card.
2. Confirm the item belongs to this station's category filter.
3. Choose a valid next state: Created, In progress, Ready to take, then Completed.
4. Use Rejected only when the item cannot be prepared.
5. Do not try to move completed or rejected work back into preparation.

If the valid action still fails, keep the card open and report the order/item ID, current state, requested state, POS station, time, and app versions.
