Revised the `populate_from` argument of the Product model's `slug` field to use only `category__name` and `name` for generation. This simplifies the slug creation logic and aligns with the updated migration `0015_alter_product_slug`.
Changed the `slug` field in the `Product` model to allow null values by setting `null=True`. This ensures better flexibility when handling cases where a slug might not be immediately available.
Made the `slug` field nullable in migration 0013 before reverting this change in migration 0014. Additionally, altered the population logic to always include `uuid`.
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.
