Fundament: ISMS-Module entfernt; Craftvia-Rollen, Module, Navigation, i18n-Split

- ISMS-Routen, Actions, Server-/Lib-Code, Komponenten, Prisma-Modelle, Seeds,
  Importer, Skripte und ISMS-Tests entfernt (Fundament bleibt: Auth, Identity,
  MFA/WebAuthn, RBAC, Audit, Mail, Storage, Backup/DSGVO, Plattform-Admin)
- Schema auf Fundament-Modelle reduziert; TenantSettings generisch (+phone/email)
- TENANT_MODELS (db.ts, backup/topology.ts) und PII-Felder ausgedünnt
- RBAC: Rollen tenant-admin/backoffice/team-lead/technician + Craftvia-Permissions
- Modul-Katalog (customers, sites, teams, work_orders, imports, field, reports,
  emergency, documents, notifications, lotse) + Navigation aus src/lib/nav.ts
- Modul-Routen mit requireModule-Layout und Platzhalterseite
- Message-Katalog je Namespace (messages/<locale>/<namespace>.json), fs-Loader
- check-module-guards: Modul-Key aus src/server/actions/<moduleKey>/
- Provisionierung, Admin-Konsole, Einstellungen, Files-Route, Mail entkoppelt
- Seed minimal (demo/demo2, Nutzer je Rolle); Fundament-Tests auf Role/
  NotificationPreference-Fixtures umgestellt
