Subject: [PATCH] fix: resolve webpack build error for nodemailer in Docker
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- next.config.ts: serverExternalPackages für nodemailer hinzugefügt
- instrumentation.ts: statischen Import durch dynamischen ersetzt, damit
  Webpack email-queue.ts (und damit nodemailer) nicht im Edge-Bundle analysiert
