Refactor content handling in GenerateContentFunction and update related models and serializers

- Enhanced GenerateContentFunction to save content in a dedicated Content model, separating it from the Tasks model.
- Updated Tasks model to remove SEO-related fields, now managed in the Content model.
- Modified TasksSerializer to include new content fields and adjusted the API to reflect these changes.
- Improved the auto_generate_content_task method to utilize the new save_output method for better content management.
- Updated frontend components to display new content structure and metadata effectively.
