fix(web): downgrade next.js 16.2.2 → 16.0.10 (hydration crash)

Next.js 16.2.2 causes React #130 on client hydration in
production standalone output. Server renders fine but client
JS crashes. Downgrade to 16.0.10 which was the last working
version. Payload CMS is fully removed from prod so the
turbopack restriction is no longer relevant.
