Refactor: code cleanup and consistency improvements

- Fix Heading4 using styled.h3 instead of styled.h4 (wrong semantic element)
- Fix switch fallthrough: add missing break after case 'h4' in Heading component
- Remove redundant iconName guard in Icon.tsx (double-checked after early return)
- Remove unintended export of internal Container styled component in HeroBlank.tsx
- Replace social-media-icons/styles barrel export with InfoCallToAction export in components/index.ts
- Standardize sibling component imports to use relative paths in MarkdownRenderer and GetInTouchSection
