Enhance hit and vote retrieval logic in API

- Implemented error handling for uninitialized knowledge base in GetHit and GetVote functions.
- Added detailed error responses for cases where hits or votes are not found.
- Updated response structures to return the retrieved hit and vote data along with associated identifiers.
