test: Product Query & Filter Engine, Item Group Page

- Test for ProductQuery engine and ProductFilters engine
- Test for engine for Item Group too
- Renamed ‘product_configurator’ to ‘variant_selector’
- Cleaned up filters.py
- Modal freeze backdrop lighter only in cart, since there’s nothing over it
- Fixed unusual spacing in variant selector dialog
- Made `get_child_groups_for_website` more readable
- Replaced ‘Configure’ with ‘Select’ for variant selection
