Migrate from Vite to Next.js 16 with Turbopack
This is a major migration from Vite to Next.js 16.0.1 for improved
performance, better SEO, and modern React features.

## Next.js Migration Changes
- Upgraded to Next.js 16.0.1 with Turbopack (from Vite 6)
- Migrated from client-side routing to App Router architecture
- Created app/ directory with Next.js page structure
- Added server components and client components pattern
- Configured standalone Docker builds for production

## Bug Fixes - React Hooks
- Fixed infinite loop in Header.tsx scroll behavior (removed lastScrollY state dependency)
- Fixed infinite loop in useCalculatorState.ts (wrapped saveState/clearState in useCallback)
- Fixed infinite loop in OffsetOrder.tsx (removed savedState from useEffect dependencies)
- Removed unused React imports from all client components

## Environment Variable Migration
- Migrated all VITE_ variables to NEXT_PUBLIC_ prefix
- Updated src/utils/config.ts to use direct static references (required for Next.js)
- Updated src/api/checkoutClient.ts, emailClient.ts, aisClient.ts for Next.js env vars
- Updated src/vite-env.d.ts types for Next.js environment
- Maintained backward compatibility with Docker window.env

## Layout & UX Improvements
- Fixed footer to always stay at bottom of viewport using flexbox
- Updated app/layout.tsx with flex-1 main content area
- Preserved glass morphism effects and luxury styling

## TypeScript & Build
- Fixed TypeScript strict mode compilation errors
- Removed unused imports and variables
- Fixed Axios interceptor types in project/src/api/wrenClient.ts
- Production build verified and passing

## Testing & Verification
- Tested calculator end-to-end in Playwright
- Verified Wren API integration working (11 portfolios fetched)
- Confirmed calculation: 5000L → 13.47 tons CO₂ → $3,206 total
- All navigation routes working correctly
- Footer positioning verified across all pages

## Files Added
- app/ directory with Next.js routes
- components/ directory with client components
- next.config.mjs, next-env.d.ts
- ENV_MIGRATION.md, NEXTJS_MIGRATION_COMPLETE.md documentation

## Files Modified
- Docker configuration for Next.js standalone builds
- package.json dependencies (Next.js, React 19)
- ts config.json for Next.js
- All API clients for new env var pattern
