Feature/atomic sturcture components

[vaibhav-cw]

What does this PR do?

• Implements the Atomic Design methodology by restructuring components into atoms, molecules, and organisms for better scalability and maintainability.
• Adds atomic components: Button (with variants and sizes), Container (for layout), Heading (typography), ResponsiveImage (Next.js Image wrapper), and Text (body text variants).
• Adds molecular components: FeatureCard, FeatureListSection, HeroSection, and TextImageSection, composed from atoms.
• Adds organism component: PageRenderer, which dynamically renders sections based on CMS data.
• Updates globals.css with custom animations (fadeIn, subtleZoom) and corresponding CSS classes for component interactions.
• Refactors app/[slug]/page.tsx to import PageRenderer from the new organisms location.
• Deletes legacy components: old PageRenderer.tsx, PageRenderer.type.ts, sectionMap.ts, and individual section files (HeroSection, FeatureListSection, TextImageSection).
• Adds comprehensive README.md documentation for the component structure, usage examples, and best practices.

What steps does your reviewer have to take to test this PR manually?

1. Check out the branch feature/atomic-sturcture-components.
2. Run the Next.js application locally and navigate to a page that uses the PageRenderer (e.g., a slug page).
3. Verify that all sections (HeroSection, FeatureListSection, TextImageSection) render correctly with the new atomic components.
4. Test interactive elements like Button variants, Heading levels, and animations (fade-in, subtle zoom) on the rendered page.
5. Ensure no console errors and that the component imports work from the new structure.
