3x3-system: match icon-row/StepArrow pattern used site-wide

Category cards were a standalone 3-card grid with red/amber/green
accents (matching the original blog post) — out of step with how
every other icon-row on the site looks. Now the same icon-above-
text + StepArrow layout as /7-tage-klarheits-check's "So
funktioniert" and /lebensuhr's phase row, and the icons are a single
brand-orange line-icon style instead of per-category colors.
