fix(site-builder): add Hero/CTA components to Layers virtual-rows registry

A grep across every component under src/components/ (not just the 12
files the original registry hardcoded) turns up three more leaf
components with the identical array-prop-as-content pattern: Hero
(HeroSimple.tsx), Call to Action (CallToAction.tsx) and CTA Section
(CTASection.tsx) all render a shared `ctas?: CtaButton[]` prop whose
items are `{ text, href, variant?, target? }`. Without this, a Hero's
CTA buttons still wouldn't appear in the Layers tree.

Verified displayName, prop name and label field against each
component's craft.props defaults and the shared CtaButton type in
sections/_cta-helpers.tsx -- all three matched exactly, no corrections
needed. A follow-up sweep for any further array-prop leaf components
found none: the only other array fields in the tree are nested one
level inside already-covered items (ContactFormField.options,
PricingPlan.features), not top-level component props.
