feat: refresh_column_async returns a job handle (#3939)

Mirrors create_index's dual surface: the blocking refresh_column keeps
returning {rows_filled, version}, and refresh_column_async returns the
same
Job handle create_index uses, running the refresh as an in-process task.
Invalid input is reported by the submitting call rather than by the job.
