Add ArthaOrbit Next.js frontend template with pages, SEO, and UI components

[Rock682]

Motivation

• Provide a frontend-only Next.js 15 fintech affiliate template optimized for SEO, EEAT, Core Web Vitals and high-conversion affiliate layouts.
• Ship a minimal production-ready site structure with common pages (home, blog, comparisons, calculators, reviews, legal pages) and monetization/affiliate hooks.
• Include developer-first project configuration for Tailwind, TypeScript and Next to make local development and deployment straightforward.

Description

• Add a README with usage and manual affiliate workflow instructions and basic run/deploy commands.
• Introduce app routes and placeholder pages under app/ including page.tsx home, about, blog, calculators, comparisons, reviews, terms, privacy-policy, disclaimer, affiliate-disclosure, contact, and admin pages.
• Add global styling and UI primitives with app/globals.css, a MainNav component in components/layout/main-nav.tsx, and a root layout in app/layout.tsx that injects JSON-LD and metadata.
• Add data and logic for the site including data/offers.ts, calculator helpers in lib/calculators/index.ts, and SEO metadata/JSON-LD in lib/seo/metadata.ts plus app/robots.ts and app/sitemap.ts.
• Add project configuration files: package.json, tsconfig.json, next.config.ts, tailwind.config.ts, postcss.config.mjs, next-env.d.ts, and an empty public/.gitkeep.

Testing

• Ran the TypeScript type check via npm run typecheck (i.e. tsc --noEmit) and it completed successfully.
