feat(ui): make steps visible at a glance; lift details card off background

The single flip-icon hid that steps existed until toggled. Replace it with an
always-visible "STEPS" summary strip below the description (open/total count,
click to expand and manage). Description is now always the card body. Give the
card a Surface2 background + LineBrush border so it separates from the window.
