fix(sync): query customers by vowels to avoid crash

- Add auth guard to getLicServerConfig() - unauthenticated callers
  now receive null config instead of DB values
- Remove non-existent 'superadmin' role from saveLicServerConfig()
  check (only 'admin' exists per project schema)
- New migration: restrict settings table WRITE to admins only
  (previously any authenticated user could overwrite licserver_api_key)

+```
+
+### A. Partner- & Unternehmens-Hierarchie
+1. Ein neu registrierter User hat die Rolle `partner` und ist zunächst keiner Firma zugeordnet.
+2. Der Administrator ordnet den User in der Admin-Oberfläche (`/admin/users`) einem Unternehmen (`companies`) zu.
+3. Nur wenn der User einer Firma zugewiesen ist (oder Admin ist), kann er Endkunden anlegen und Bestellungen aufgeben.
+
+### B. Endkunden-Verwaltung (`/my-customers`)
+- **Firmenweite Sicht**: Da `end_customers.partner_id` on `companies.id` verweist, sehen alle Mitarbeiter desselben Unternehmens dieselben Endkunden.
+- **DSGVO Anonymisierung**: Endkunden können unwiderruflich anonymisiert werden. Dabei werden sensible Daten mit `[GELÖSCHT]` überschrieben und `is_anonymized` auf `true` gesetzt. In existierenden Bestellungen (`orders.customer_data`) bleiben die Daten zu steuerlichen Zwecken unverändert.
+
+### C. Bestell-Wizard & Validierung (`/order`)
+- **Kategorie-Pflichten**: Wenn eine Produktkategorie als `is_required` definiert ist, muss ein Produkt ausgewählt werden.
+- **Abhängigkeiten (Requirements)**: Ein Modul oder Produkt kann andere Module/Produkte voraussetzen (z.B. Modul B erfordert Modul A). Das System prüft dies client- und serverseitig.
+- **Top-Down State-Management**:
+  - Die Wahl eines Basis-Produkts steuert die Sichtbarkeit und Wählbarkeit aller Module (Top-Down). Modul-Auswahlen dürfen niemals die Liste der wählbaren Basis-Produkte beeinflussen (Verhinderung von UI-Deadlocks).
+  - **Auto-Reset & Kaskaden-Bereinigung**: Beim Wechsel des Basis-Produkts in `selectProduct` werden inkompatible Module in anderen Kategorien automatisch über eine Kaskaden-Bereinigung (Filterung der `moduleIds` basierend auf den `exclusions` des neuen Produkts) deselektiert.
+  - **Sichtbarkeits- & Wählbarkeits-Garantie**: Basis-Produkte werden im UI niemals durch Modulausschlüsse ausgeblendet. Nachgelagerte Produkte/Module, die mit dem ausgewählten Basis-Produkt inkompatibel sind, erhalten im JSX das `disabled`-Attribut und sind nicht anklickbar (Sperrung von "Kein Backoffice" bei "Small Business"). Klicks auf Module haben keinerlei Rückwirkung auf die Basis-Produkt-Auswahl.
+  - **Radio-Button-Verhalten (allow_multiselect = false)**: Falls eine Kategorie keine Mehrfachauswahl erlaubt, wird bei Auswahl eines neuen Moduls das zuvor ausgewählte Modul dieser Kategorie automatisch abgewählt.
+- **Snapshot-Architektur**: Sobald eine Bestellung aufgegeben wird, werden die Kundendaten (`CustomerSnapshot`) und Produktkonfigurationen (`OrderSnapshot` samt Preisen und Modulversionen) in `orders` als JSONB-Snapshots eingefroren. Preisänderungen im Katalog haben keinen Einfluss auf bestehende Bestellungen.
+
+### D. Bestellungs-Verwaltung & Statusübergang
+- **Sichtbarkeit**: Partner sehen in `/my-orders` alle Bestellungen aller Mitarbeiter ihrer Firma.
+- **Bearbeiten**: Unvollständige Bestellungen (`status != 'completed'`) können von jedem Mitarbeiter der jeweiligen Firma nachträglich editiert werden.
+- **Admin-Workflow**: Admins sehen in `/admin/orders` alle Bestellungen global, können den Status ändern (z.B. von *Eingegangen* auf *In Bearbeitung* oder *Abgeschlossen*) und PDF-Rechnungen manuell herunterladen.
+- **Statusänderungs-Mails**: Bei jedem Statusübergang wird automatisch eine Benachrichtigungs-E-Mail an den Besteller geschickt.
+
+---
+
+### E. Multi-Kassen-Warenkorb & Checkout-Split
+- **Endpunkt / Server Action**: `POST /api/orders/checkout` sowie Server Action `checkoutAction` in `app/actions/checkout.ts`
+- **Funktionsweise**:
+  - Empfängt ein Array von `items` (Kassenkonfigurationen).
+  - Validiert Auth und Partner-Firma Zuweisung.
+  - Generiert einen `order_hash` zur Vermeidung von Doppelübermittlungen (Idempotenz-Guard).
+  - Teilt die Konfigurationen nach `billingInterval` / `billingType` auf (Kauf vs. Abo).
+  - Erstellt separate Orders in der Datenbank:
+    - Typ `purchase`: Anfrage für Kauf-Lizenzen (Zahlungsart: Vormerkung/Angebot).
+    - Typ `subscription`: Anfrage für Software-Abonnement (Zahlungsart: SEPA).
+  - Friert für jede Order einen konsolidierten `order_data` (JSONB) und `customer_data` (JSONB) ein.
+  - Triggert die PDF-Erstellung und den E-Mail-Versand unabhängig für jede generierte Order (gibt Order-IDs für Post-Processing zurück).
+
+---
+
+### F. PDF-Rechnungsgenerierung & Mail-Versand (Post-Processing)
+- **Entkopplung & Asynchronität**: Die Generierung der PDFs und der E-Mail-Versand sind vollständig aus dem synchronen Checkout-Flow entkoppelt. Der Checkout liefert dem Frontend sofort nach Speicherung in der DB eine Erfolgsmeldung zurück. Die Generierung und der Versand werden asynchron im Hintergrund (via unblockiertem Promise-Worker) ausgeführt, um SMTP-Latenzen abzufangen.
+- **Snapshot-Exklusivität**: Die PDF-Generierung erfolgt ausschließlich auf Basis der in `orders.order_data` und `orders.customer_data` eingefrorenen Snapshots.
+- **Layout-Unterscheidung**:
+  - **Typ `purchase` (Kauf)**:
+    - Generiert eine klassische **Anfragebestätigung Kauf**.
+    - Weist die einmalige Gesamtsumme aus.
+  - **Typ `subscription` (Abonnement)**:
+    - Generiert eine **Anfragebestätigung Abonnement**.
+    - Weist monatlich wiederkehrende Kosten aus.
+- **Archivierung & Benachrichtigung**:
+  - Hochladen des PDFs in den Supabase Storage (`invoices` Bucket).
+  - E-Mail-Versand mit PDF-Anhang an den Partner.

+# Sicherheitskonzept (RLS - Row Level Security)
+
+RLS ist auf Datenbankebene in Postgres implementiert und erzwingt Datenisolierung:
+
+- **Unternehmen (`companies`)**: Authentifizierte Benutzer dürfen nur die Unternehmen lesen.
+- **Endkunden (`end_customers`)**:
+  - `USING (partner_id = (SELECT company_id FROM public.users WHERE id = auth.uid()))`
+  - Partner sehen und modifizieren nur Endkunden, deren `partner_id` mit der `company_id` des angemeldeten Benutzers übereinstimmt.
+- **Bestellungen (`orders`)**:
+  - `USING (company_id = (SELECT company_id FROM public.users WHERE id = auth.uid()))`
+  - Partner sehen und modifizieren nur Bestellungen, die ihrer Company zugewiesen sind (sie müssen einer Company zugeordnet sein).
+  - Jede Bestellung wird bei der Erstellung automatisch der Company des Erstellers zugewiesen.
+  - Admins haben uneingeschränkten Zugriff und können Bestellungen nachträglich anderen Companies zuweisen.
+- **Lizenzen (`licenses`)**:
+  - Partner sehen nur Lizenzen von Endkunden, die ihrer Company zugeordnet sind.
+
+- **Systembenutzer (`users`) & Rollen-Schutz**:
+  - Authentifizierte Nutzer dürfen nur ihr eigenes Profil lesen.
+  - Admins dürfen alle Benutzer lesen. Zur Vermeidung von unendlichen RLS-Rekursionen auf der Tabelle `users` wird die Admin-Zuweisung über die Security-Definer-Funktion `public.is_admin(user_id)` geprüft, welche RLS auf Datenbank-Ebene umgeht.
+  - Rollenschutz-Trigger (`check_user_role_escalation`): Jegliche Änderung der Spalte `role` oder Zuweisung der Rolle `'admin'` ist auf API-Ebene für normale Nutzer gesperrt. Updates/Inserts der Rolle werden ausschließlich von der `service_role` (Backend Admin-Client) akzeptiert, um Privilegien-Eskalation zu verhindern.

+- **Array-Validierung & Split (basketItems)**: Stellt sicher, dass das vollständige Array an konfigurierten Kassen (`basketItems`) validiert und verarbeitet wird (nicht nur ein Single-Produkt).
+- **Kauf-Warenkorb**: Verifiziert, dass ein reiner Kauf-Warenkorb (`one_time`/`purchase`) exakt eine Order erzeugt.
+- **Abo-Warenkorb**: Verifiziert, dass ein reiner Abo-Warenkorb (`monthly`/`subscription`) exakt eine Order erzeugt.
+- **Gemischter Warenkorb**: Stellt sicher, dass ein gemischter Warenkorb korrekt in zwei separate Bestell-Gruppen aufgeteilt wird (Kauf-Items & Abo-Items separat).

+- **Status**: Accepted
+- **Date**: 2026-07-06
+- **Context**: Die Tabellen `pos_modules` und `licenses` wurden von einem alten bzw. externen Service genutzt. Im aktuellen Webshop-Frontend werden sie nicht benötigt und führen zu unnötiger RLS- und Integritäts-Komplexität.
+- **Decision**: 
+  - Erstellen einer SQL-Migration zum Löschen (`DROP`) von `licenses` und `pos_modules`.
+  - Anpassung der Integritätsprüfungs-Funktionen `check_database_integrity` und `repair_database_schema` zur Entfernung dieser Relationen.
