fix(accessibility): Correct heading hierarchy and identical links

Phase 4.4 Accessibility fixes:
- ContactFormRenderer: Change h6 info-labels to span (WhatsApp, Email, Location)
- RelatedPostRenderer: Change h5 card-title to span (semantic hierarchy)
- top-notification-bar schema: Change link_url default from # to /suscripcion-vip
  (identical links must have same destination)

Fixes: "Headings not in sequential order" and "Identical links have different purposes"
