Enhance Content Management with New Taxonomy and Attribute Models

- Introduced `ContentTaxonomy` and `ContentAttribute` models for improved content categorization and attribute management.
- Updated `Content` model to support new fields for content format, cluster role, and external type.
- Refactored serializers and views to accommodate new models, including `ContentTaxonomySerializer` and `ContentAttributeSerializer`.
- Added new API endpoints for managing taxonomies and attributes, enhancing the content management capabilities.
- Updated admin interfaces for `Content`, `ContentTaxonomy`, and `ContentAttribute` to reflect new structures and improve usability.
- Implemented backward compatibility for existing attribute mappings.
- Enhanced filtering and search capabilities in the API for better content retrieval.
