fix(#P7-P8): Statische Route-Permissions auf Backend-/Manifest-Wahrheit gestellt — /communication comm:read (Phantom communication:read entfernt), /mail/settings mail:config (Backend verlangt config), /import-export import_export:read (Core-Modul, kein Plugin — Kritik-Aussage korrigiert), /activity audit:read (Phantom activity:read entfernt, Seite nutzt Audit-API), /wiki wiki:read (vorher ungeschützt); Regressionstest routePermissions.test.ts 6/6; Gates: tsc 0, Production-Build exit 0
