If a DAG is already in a paused state and we runairflowctl dags pause dag_id again, it still shows the pause command executed. I believe that if the DAG is already paused, it should instead display that the dag_id is already in a paused state.

I’d love to hear your thoughts — if you agree, I’ll work on implementing that change.
