Refactor data integrity checks in hadis seeding command

- Improved the process for identifying and fixing empty slugs in NarratorLayer by utilizing raw SQL for more reliable detection.
- Enhanced logging to provide clear feedback on the number of records found and fixed, including error handling for any issues encountered during the slug update.
- Streamlined the slug fixing logic to directly address problematic entries, improving overall data integrity in the seeding process.
