feat: Complete Stage 2 frontend refactor

- Removed deprecated fields from Content and Task models, including entity_type, sync_status, and cluster_role.
- Updated Content model to include new fields: content_type, content_structure, taxonomy_terms, source, external_id, and cluster_id.
- Refactored Writer module components (Content, ContentView, Dashboard, Tasks) to align with new schema.
- Enhanced Dashboard metrics and removed unused filters.
- Implemented ClusterDetail page to display cluster information and associated content.
- Updated API service interfaces to reflect changes in data structure.
- Adjusted sorting and filtering logic across various components to accommodate new field names and types.
- Improved user experience by providing loading states and error handling in data fetching.
