Refactor search response structure and add get_talk endpoint

- Updated SearchResponse to return results with 'id' instead of '_id'.
- Introduced new endpoint /api/talk/{talk_id} to fetch individual talk documents.
- Enhanced TalkHit schema to use 'id' as the field name with an alias for '_id'.
- Cleaned up debug print statements in search function for clarity.
