This change modifies the `slug` field in the `Product` model to also populate from the `UUID` field, ensuring enhanced uniqueness and consistency. The migration file is included to apply this change to the database schema.
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.
