Export-Metadaten: Umlaut-Fix, xmpMM:VersionID + History

- dc:rights und xmpRights:UsageTerms: Empfaenger -> Empfänger (echte Umlaute)
- Scope-Labels: Vollstaendiger Bericht -> Vollständiger Bericht (zwei Stellen)
- DOCX-Fallback-Text: verfuegbar -> verfügbar
- xmpMM:VersionID: Snapshot-Count der Lage (Proxy fuer Berichts-Revision).
  Router laedt COUNT(*) FROM incident_snapshots und reicht es durch.
- xmpMM:History: Audit-Event pro Export als rdf:Seq-Eintrag mit Timestamp,
  softwareAgent, InstanceID, Scope und Version. Single-Event-Format aus
  pragmatischem Grund (pikepdf-API unterstuetzt keine nativen stEvt-
  Strukturen; Raw-XML-Injection waere dafuer noetig).
