[FEATURE]: Migrate from Vite react to Nextjs and tailwind v4

[DeveloperAmrit]

Feature and its Use Cases

• Next.js has better SEO and development-deployment workflow, so migrating to NEXT js is a good idea
• Server-side rendering with NEXT js provides much better SEO
• The latest Tailwind version (v4+) is lighter and much better than what is currently being used.
