fix(dashboard): enable scroll on small screens in Control Dashboard

Removed h-full and overflow-auto from the root grid div. h-full was
constraining the grid to the viewport height, causing CSS grid to
shrink rows to fit instead of overflowing. Parent <main> already has
overflow-auto, so removing the height constraint lets content expand
naturally and scroll correctly on small screens.
