Refactor and archive deprecated slots; update migration records

- Removed deprecated slots: storage_security_level, version_number, video_comment, visiting_hour, was_asserted_by, was_revision_of, writing_system.
- Archived corresponding YAML files for deprecated slots with detailed migration notes.
- Updated slot definitions for has_collection and encompassing_body to reflect new naming conventions and temporal patterns.
- Enhanced metadata extraction in index_persons_qdrant.py to include WCMS registration and data sources.
- Modified hybrid_retriever and multi_embedding_retriever to support filtering by WCMS registration status.
