Add bulk photo deletion feature for products.

Allows selecting and deleting multiple photos at once via checkboxes
and an AJAX endpoint. Key features:
- Checkboxes next to each photo in edit form
- Delete button that shows only when photos are selected
- AJAX request with JSON payload and success confirmation
- DOM removal and counter update after deletion
- Uses existing ImageProcessor cleanup logic

Files changed:
- product_form.html: Added checkboxes and delete button with JS handler
- photo_management.py: Added product_photos_delete_bulk AJAX view
- urls.py: Added /product/photos/delete-bulk/ endpoint
- views/__init__.py: Exported new function
