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.
