build(frontend): migrate CRA to Next.js (CSR lift-and-shift)

Wave 6. Swaps react-scripts' build/dev tooling for Next.js while keeping the app's actual routing/rendering model unchanged -- the app is almost entirely behind auth with no proven SSR/SEO need, so a real App Router rewrite would touch ~90 files for zero user-visible benefit. - next.config.js: output:'export' (static HTML+JS, same "single index.html served by nginx with try_files fallback" deploy as CRA). - app/layout.tsx + app/page.tsx: root shell ports public/index.html's <head>, mounts the whole existing App tree client-only (ssr:false) since it reads window/localStorage during initial render and Next's static prerender would otherwise execute that on the server. - Renamed src/pages/ -> src/views/ (Next's Pages Router auto-detects any `pages/` dir under the app root and tried to build our React Router page components as its own routes). - REACT_APP_* -> NEXT_PUBLIC_* across code, .env.development, Dockerfile, docker-compose.yml build args. - Replaced the CRA SVGR import (`ReactComponent` from .svg, unsupported under Turbopack) with a small inline JobbjaktMark component. - TypeScript 4.9 -> 5.9 (MUI v8's type-checked build needs syntax 4.9's parser rejects; CRA never hit this because babel doesn't type-check). - Dropped CRA-only files (index.tsx, reportWebVitals, react-app-env.d.ts, public/index.html); kept react-scripts as the Jest test runner only (next/jest migration not needed -- the existing config already works). Verified: `next build` static export succeeds, `next dev` serves the landing page and client-side routes (login etc.) correctly, all 57 frontend tests + 172 backend tests still green. Known caveat: deep-linking straight to a sub-route (e.g. /login) 404s in `next dev` since there's no server route for it -- the app only ever mounts at "/". Production is unaffected: nginx's existing try_files fallback still serves index.html for any path.
