Summary

Updated the default session type to None in the get_sessions and get_runs functions. This change allows fetching sessions and session runs using only the session_id, without specifying db_id or type. It is useful for scenarios where multiple session types share the same db_id, enabling retrieval of different types of sessions or session runs with a single API call.
