fix: hero neuro-audit v2 — missing transparent states + icon thickness

- Add :focus-visible, :active states on all buttons (CTA, sticky-cta, btn-primary)
- Add transition (200ms ease) on sticky-cta__btn
- Match btn-primary:hover shadow to new solid base
- Increase social-proof icon stroke-width 2→2.5 for visibility
