IAV-1279: Analytics coming-soon page redesign + WooCommerce readOnly integration card

• Analytics page: Full redesign of the coming-soon screen — blur-to-focus shimmer animation on "BIENTÔT / DISPONIBLE" using the project's purple-blue theme (#8B5CF6 / #3B82F6), animated background orbs, feature pills, and pulsing dots. Accent rendering fixed via increased lineHeight + paddingTop.

• IntegrationCard: Added readOnly prop — hides the toggle and connect/modify button without applying the disabled comingSoon overlay.

• IntegrationGrid / IntegrationSection: Propagate readOnly through the platform config. WooCommerce added as a readOnly display-only card.
