Refactor server and embedding provider to improve modularity

- Modify `serve()` function to accept a pre-configured QdrantConnector
- Update `create_embedding_provider()` to simplify model name handling
- Improve error handling and parameter passing in server tools
- Restructure main function to create connector and server more explicitly
