Fix: Include imageUrl/imageUrlBack in database select query

- Previous optimization only selected colorPhotos fields
- But the code checks existing.imageUrl to decide if print area should update
- imageUrl/imageUrlBack were undefined, breaking the print area update logic
- Now properly includes these fields in the select so the check works
