Migración completa a Clean Architecture con componentes funcionales

- Reorganización de estructura: Admin/, Public/, Shared/, Schemas/
- 12 componentes migrados: TopNotificationBar, Navbar, CtaLetsTalk, Hero,
  FeaturedImage, TableOfContents, CtaBoxSidebar, SocialShare, CtaPost,
  RelatedPost, ContactForm, Footer
- Panel de administración con tabs Bootstrap 5 funcionales
- Schemas JSON para configuración de componentes
- Renderers dinámicos con CSSGeneratorService (cero CSS hardcodeado)
- FormBuilders para UI admin con Design System consistente
- Fix: Bootstrap JS cargado en header para tabs funcionales
- Fix: buildTextInput maneja valores mixed (bool/string)
- Eliminación de estructura legacy (src/, admin/, assets/css/componente-*)
