The Actions panel rows carried a drag payload that only the reorder drop understood, so dropping a row on the footer trash or on Create new action did nothing. The footer buttons now take the drop (the trash deletes the dragged row, the plus duplicates it right after itself) through shared delete_row and duplicate_row helpers that also keep the selection and disclosure rows right, with a hover highlight and the same recording rules as the buttons. Tests drive real pointer drags for step and action rows onto both buttons, a drop on empty space, and a drop on the trash while recording.
