Enhanced the `deepl_translate` management command with improved placeholder handling, error messages, and support for missing translations. Added `human_readable_id` and `is_business` attributes to the `Order` model, updating associated admin configurations to reflect these changes.
Removed invalid `select_related` and `prefetch_related` chaining on the product query. This resolves potential errors in fetching related data and ensures proper functionality.
Introduce a unique, auto-generated slug field to the Product model, populated from category, brand, and name. Update core filters, serializers, sitemaps, and GraphQL object types to support the new slug functionality. Also, enforce HTTP-only cookies for session, CSRF, and language for improved security.
