GAP WP3.0: Generisches, editierbares Register-Datenmodell + Editor

Verwaltete Register (GAP-Report §5.2) sind nicht mehr nur benannte Dokumente,
sondern editierbare Register mit Pflichtspalten und Cross-Links.

- Schema: ManagedRegister (code, title, columns JSON, reviewCycle, responsible,
  supplierLink/assetLink) + RegisterRow (values JSON, supplierRef, assetRef).
  Migration + RLS; in TENANT_MODELS.
- import-managed.ts: 7 generische Register (REG-PROJECTS, -SENS-ROLES, -AUDIT-PLAN,
  -EXT-SERVICES, -SW-WHITELIST, -CRIT-SERVICES, -NET) mit definierten Pflichtspalten
  + Cross-Link-Flags; legt Register-Dokument (Bibliothek/Link) UND ManagedRegister-
  Definition idempotent an (RegisterRow bleibt bei Re-Import erhalten).
- actions/register.ts: addRegisterRow/updateRegisterRow/deleteRegisterRow
  (Modul policies, policy:write; Werte gegen die Pflichtspalten, optional Lieferant/Asset).
- components/generic-register.tsx: editierbare Zeilen-Tabelle + Cross-Link-Selects
  (Lieferant = Asset SUPPLIER/IT_SERVICE, Asset = alle); in /policies/[code] eingebunden.

Browser-verifiziert: REG-EXT-SERVICES rendert 7 Spalten + Lieferant/Asset-Selects;
Eintrag anlegen persistiert alle Werte. tsc + lint + build + Guard-Check grün.
