fix(07): UAT fixes — SMTP test email, DKV routing, Exchange domain field

- SMTP: add test-to field, send real email via sendMail() instead of verify() - SMTP: fix no_auth warning shown as error for open-relay servers - DKV: register dkv-fleet in MODULE_REGISTRY (fixes "Modul nicht gefunden") - DKV: add dynamic [category]/[moduleSlug]/settings + vehicles sub-routes - DKV: settings/vehicles links use useParams for consistent URLs - DKV: add gear icon settings link to module main page - DKV: rename module to "DKV-Rechnung" in seed + translations - DKV: add optional domain field for Exchange (WebCredentials 3rd arg) - DKV: hide IMAP-only fields (Port/Verschlüsselung/Ordner) when Exchange selected - DKV: hide Exchange-only field (Domain) when IMAP selected - Prisma: add domain column to DkvModuleConfig Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

 ## Tests

 ### 1. Cold Start Smoke Test
 expected: Kill any running services. Start fresh via docker compose up. API-Container startet ohne Fehler, Prisma-Verbindung gelingt, /api/health oder ein einfacher API-Call liefert eine Antwort zurück. Keine Crash-Logs in docker compose logs tessera-ctl-api-1.
-result: issue
-reported: "DB-Container nach Start nicht in docker compose ps sichtbar. API loggt wiederholt P1001: Can't reach database server at db:5432 bei Requests (ModuleRegistry, Dashboard, LdapSync, WidgetInstance). NestJS startete und Admin-Seed lief durch, aber DB-Verbindung bricht danach ab."
-severity: major
+result: pass
+note: "docker compose down && docker compose up -d: DB healthy → API healthy → Web up. Früheres P1001 war externaler SIGKILL auf DB-Container, kein Code-Defekt."

 ### 2. Settings-Sidebar: Allgemein-Kategorie
 expected: In der Settings-Seitenleiste (z.B. unter /settings/general/smtp) erscheint eine neue Kategorie "Allgemein" mit einem Link "SMTP" — platziert oberhalb der bestehenden "Dashboard"-Kategorie.
-result: [pending]
+result: pass

 ### 3. SMTP-Einstellungen-Seite aufrufen
 expected: /settings/general/smtp öffnet eine Seite mit einem Formular, das 6 Felder enthält: Host, Port, Verschlüsselung (Dropdown), Benutzername, Passwort (mit Show/Hide-Toggle), Absenderadresse. Das Passwort-Feld ist leer (niemals vorausgefüllt).
-result: [pending]
+result: pass

 ### 4. SMTP-Konfiguration speichern
 expected: Formularfelder ausfüllen und "Speichern" klicken → kurze Erfolgs-Meldung erscheint ("Gespeichert" o.ä.). Beim nächsten Laden der Seite sind Host, Port, Benutzername, Absenderadresse wieder befüllt — Passwort bleibt leer (nur hasPassword-Indikator).
-result: [pending]
+result: pass

 ### 5. SMTP-Verbindungstest
 expected: "Verbindung testen"-Button anklicken → inline Feedback erscheint (grün bei Erfolg, rot bei Fehler). Die Meldung verschwindet automatisch nach ca. 6 Sekunden.
-result: [pending]
+result: pass
+note: "Feld 'Test-E-Mail an' ergänzt. Echter Versand via sendMail(). Grüne Bestätigung erscheint korrekt."

 ### 6. DKV Fleet Modul — Hauptseite
 expected: /modules/dkv-fleet zeigt drei Bereiche: (1) Verarbeitungshistorie-Tabelle mit Spalten Datum/Rechnungsnummer/Status/Fahrzeuge, (2) Export-Dateiliste, (3) "Jetzt prüfen"-Button. Bei leerem System zeigt die Tabelle einen leeren Zustand (kein Crash).
-result: [pending]
+result: pass
+note: "MODULE_REGISTRY-Eintrag für dkv-fleet ergänzt. URL: /modules/fleet/dkv-fleet"

 ### 7. DKV Einstellungen — Posteingang-Konfiguration
 expected: /modules/dkv-fleet/settings zeigt einen Tab "Posteingang" mit Formular für IMAP- oder Exchange-Zugangsdaten (Host, Port, Benutzername, Passwort). Formular kann ausgefüllt und gespeichert werden.
