refactor: update researcher API endpoints to include batch search and statistics functionality

- Removed deprecated search logic and replaced it with a new structure for handling researcher statistics.
- Introduced new schemas for batch search requests and responses.
- Enhanced the search endpoint to return publication statistics alongside researcher data.
- Updated docker-compose file to remove unnecessary versioning.
