Subject: [PATCH] Fix: next.config.ts -> next.config.js (Prod-Image hat kein
 TypeScript)

Das runner-Stage uebernimmt node_modules aus dem deps-Stage (npm ci --omit=dev),
enthaelt also kein TypeScript. Next.js konnte die next.config.ts deshalb zur
Laufzeit nicht transpilieren und brach beim Start ab ("Failed to transpile
next.config.ts"). Die Config setzt nur turbopack.root, was fuer `next start`
ohnehin irrelevant ist - daher gleichwertig als CommonJS-JS-Datei.
