Migrate web app from CRA to Next.js for SSR and SEO

[Copilot]

The web app needed SEO capabilities after prerender.io trial expiration. Migrated from Create React App to Next.js 13 with server-side rendering to enable search engine crawling with proper meta tags.

Changes

Next.js Setup

• Installed Next.js 13, upgraded React 17→18
• Created pages/ directory with routes matching existing structure
• Added _app.js for Redux provider, _document.js for HTML structure
• Configured next.config.js with SASS support

SSR Compatibility

• Wrapped browser API access in typeof window !== 'undefined' checks
• Updated createExcerpt(), Home, MainCV components for SSR safety
• Migrated react-helmet to Next.js Head component
• Dynamic routes use getServerSideProps for on-demand rendering

Routing

• Created NavLink compatibility wrapper for Next.js router
• Replaced react-router-dom with Next.js Link and useRouter
• All existing routes preserved with same paths

Deployment

• Updated Dockerfile to run Next.js server instead of static build
• Created start.sh to orchestrate nginx (hub), backend, and Next.js server
• Next.js runs on port 8080, backend on 8082, hub on 8081

Build Output

Route (pages)                              Type      Size
/                                          Static    12.6 kB
/blog/[id]                                 SSR       45.2 kB  
/cv/[language]/[id]                        SSR       4.41 kB
/portfolio/[language]/[position]           SSR       2.4 kB

Static pages pre-rendered at build time. Dynamic pages server-rendered on request with proper meta tags for crawlers.

Preserved

• All React components in src/ unchanged
• Redux state management
• Existing styles and UI
• API integration layer

<issue_title>Migration to Next.js</issue_title>
<issue_description>Because web is a public-facing website, we need SEO, so that means server-side rendering is necessary. Up to this point, prerender.io was used for SEO, but that trial has expired.

• Convert the app into a Next.js app with server side rendering, mainly for SEO. All other back-end services should remain intact.
• Styling will remain the same
• Minimal changes to keep components and front-end logic the same, just server-side render for crawlers</issue_description>
