This commit introduces support for uploading optional video files to products and image files to blog posts. Enhanced admin interfaces were added to preview these files directly. Also includes adjustments to GraphQL types and serializers to expose the new fields.
update `slug` field for `Post` model using `TweakedAutoSlugField` to improve auto-slug behavior with Unicode and additional options. Add detailed `attribute_values` to demo products for enriched metadata. Update dependencies for stability and features.
add feed generators for Google Merchant, Amazon Seller, Yandex Market, and Yandex Products. Includes a shared base class (`BaseFeedGenerator`) for common functionality, such as product retrieval and validation. Each generator supports format-specific output and handles platform-specific requirements.
This change simplifies the creation of product feeds for multiple marketplaces.
Introduce `EmailImage`, `EmailTemplate`, and `EmailCampaign` models for enhanced email management, including campaign tracking and one-click unsubscribe tokens. Added multilingual fields for email templates and improved accessibility with image alt text. Also adapted `Post` content fields to support translations.
