fix(security): F23 (Astra P1) — DB-weiter Restore nur noch fuer System-Admins

Vorher: POST /api/v1/backups/{id}/restore war ueber automation:admin
eines Mandanten erreichbar — der Restore bearbeitet aber die GESAMTE
geteilte Datenbank ohne Mandantenfilter. Ein Tenant-Admin haette den
Zustand aller Mandanten ueberschreiben koennen.

Fix: Restore-Route auf require_admin umgestellt (echter System-Admin:
is_system_admin oder *:* via RBAC). Listen/Erstellen/Loeschen von
Backups bleibt mandantenbezogen auf automation:admin.

Abnahme (Astra): Ein Tenant-Admin kann keinen Gesamtrestore ausloesen —
erfuellt (Route-Introspektions-Tests pinnen die Verdrahtung).

Tests: test_s1_security_guards.py 12/12 (2 neue F23-Tests: restore nutzt
require_admin, restore nutzt NICHT require_permission).
