fix(combos): free-stack template first, 2x2 grid, green highlight badge

- Move 'Free Stack ($0)' to position 1 in COMBO_TEMPLATES (was 4th, invisible in 3-col grid)
- Add isFeatured flag to free-stack for special styling
- Change template grid: grid-cols-3 → 2x2 (sm:grid-cols-2) — all 4 templates visible
- Free Stack: green border/bg (emerald), FREE badge, larger text size
- Other templates: hover styles preserved, → arrow on Apply link
- Increase templates section padding
