scripts: backup-db.sh akzeptiert Container-Name + Auto-Detect-Pfad

Browse Source 
Vorher waren Container-Name + BACKUP_DIR hardcoded auf prod-Werte
(gwoe-antragspruefer / /opt/gwoe-antragspruefer/backups). Auf dem dev-Server
hat das Skript via git pull deshalb in den prod-Pfad geschrieben und gegen
den prod-Container geredet — dev hatte effektiv keinen eigenen Dump.

Fix:
- Container-Name als optionales $1-Argument (Default: gwoe-antragspruefer)
- BACKUP_DIR aus Skript-Pfad abgeleitet (parent-of-scripts/.../backups)
- Cron auf dev muss mit Argument 'gwoe-antragspruefer-dev' aufrufen

#
# Auto-Detect: BACKUP_DIR wird aus dem Skript-Pfad abgeleitet
# (parent-of-scripts/.../backups), damit die gleiche Datei via
# `git pull` auf prod und dev funktioniert ohne pfad-spezifisches Hardcoding.
