The panel footer's delete and review-toggle controls were icon-only ~16px
hit areas. After #722 removed the on-canvas delete button, the panel delete
button became the only touch-reachable delete path, so it must meet the WCAG
2.2 §2.5.8 minimum target size (44×44px). Give both icon-only footer actions
a >=44px inline-flex hit area with negative margins so the row layout and the
visible icon size are unchanged.
