Optimize: switch to output:'standalone' + slim runner image

Browse Source 
Vorher: 1.22 GB Image (volle node_modules im Container).
Nachher: ~150 MB (Next.js erzeugt unter .next/standalone einen
selbst-enthaltenden Server-Tree mit nur den Runtime-Dependencies).
Dockerfile kopiert standalone-Output + .next/static + public,
entfernt node_modules/package.json/src-Copy, startet mit 'node server.js'.
