refactor: Aktualisierung der DefaultRSAKeyNameFormatter Signatur und Logik in RSAFactory

Browse Source 
- Die Methode `DefaultRSAKeyNameFormatter` wurde geändert, um einen `visibilityTag`- und `expiration`-Parameter aufzunehmen.
- Redundante bedingte Logik für das Anhängen von Tags wurde entfernt und der Formatter für bessere Lesbarkeit und Skalierbarkeit umstrukturiert.
- Gewährleistung der Abwärtskompatibilität mit der Versionierung durch bedingte Behandlung von `passwordVersion`.
