CI: Fuegt automatisiertes Nightly-Release und Testing-Registry-Publish hinzu, behebt Zeitzone bei geplanten Workflows

- Neuer Workflow "nightly-pr.yaml": Erstellt und merged taeglich automatisch
  einen Pull Request von dev nach nightly (09:00 Uhr Europe/Berlin); legt den
  nightly-Branch bei Bedarf initial von dev an.
- Neuer Workflow "nightly.yaml": Testet, paketiert und veroeffentlicht bei
  Aenderungen auf nightly eine Pre-Release-Version (-nightly.<Zeitstempel>)
  in die Gitea Cargo Registry; erstellt bewusst kein Gitea-Release.
- testing.yaml veroeffentlicht nun zusaetzlich eine Pre-Release-Version
  (-testing.<Zeitstempel>) in die Gitea Cargo Registry, zusaetzlich zum
  bisherigen Preview-Release mit Crate-Anhang.
- Beide Versions-Suffixe sind SemVer-Pre-Releases, wodurch Renovates
  Standardverhalten (ignoreUnstable) sie automatisch ignoriert.
- CRON_TZ=Europe/Berlin in security-scan.yaml und trufflehog-scan.yaml
  ergaenzt: Gitea Actions interpretiert schedule-Cron sonst in der lokalen
  Zeitzone des Gitea-Servers statt in der beabsichtigten Zeitzone.
