feat(repository): add TagID and IsRecommended fields to vector embeddings

- Introduced `TagID` and `IsRecommended` fields across various repository implementations (Elasticsearch, Milvus, Postgres, Qdrant, SQLite) to enhance document categorization and recommendation capabilities.
- Updated the logic for handling `IsEnabled` to ensure it reflects the actual state from the source data.
- Adjusted the knowledge service to incorporate the new `IsRecommended` field, improving the indexing process for knowledge chunks.

These changes enhance the flexibility and functionality of document retrieval and indexing across the application.
