Fix: Handle image removal in product editor

- Add support for removeImage/removeImageBack flags in updateProduct action
- When Remove button is clicked, client sets isRemoved=true to hide UI
- Server action checks removeImage/removeImageBack form fields and sets imageUrl/imageUrlBack to null
- Also reset printArea to default when image is removed
- Tested: Remove button now successfully clears images and persists changes to database
