feat(legal): Als-Entwurf-kopieren für Rechtstexte

POST /api/admin/legal-documents/{id}/copy-as-draft übernimmt Titel +
Inhalt des Quelldokuments und legt einen neuen Entwurf mit
nächster Versionsnummer an. Funktioniert für alle Status (draft/published/archived).

UI: Copy-Button (⎘) in jeder Dokumentzeile; nach Kopie wird die
Liste automatisch aktualisiert und der neue Entwurf ist sichtbar.

version: 0.8.72
module:  legal_documents 1.1.0
