Replace manual secret generation instructions with keygen.sh recommendation.
Before:
# Secrets generieren:
# openssl rand -base64 32
After:
# EMPFOHLEN: Automatische Konfiguration mit:
# ./keygen.sh
This makes it clearer that keygen.sh is the preferred way to set up
the environment, as it generates all secrets and creates a complete
.env file automatically.

The keygen.sh script expects .env.example (with leading dot), not env.example.
This fixes the error when running keygen.sh.
