feat: Schlüssel und gemeinsamer Kern für Sprachnotizen (T7 L2 Tasks 5+6)

Task 5: Schlüsselbund-Zweck voice (VOICE_ENCRYPTION_KEY), AES-256-GCM-
Hilfen für Text und Bytes mit AAD capture:<id>:<art>, voice-config
(Modell, Tageslimit, Aufnahme, Whisper-Grösse) und anthropic-config
(nie geloggt, nur worker/all), Startprüfung verlangt den Schlüssel in
Produktion in jeder Rolle, rekey versiegelt offene Sprachnotizen neu
(Audio einzeln gelesen, CAS mit Status), Secret-Vorlagen und
ensure-secrets.sh ergänzt.

Task 6: Text-Normalisierung und Bereinigung (Steuer- und Formatzeichen,
Codepoint-Kürzung), Zitatprüfung mit Dezimalzahlen als ein Wort
(Ruling 7), Felderliste passend zu CreateInspectionDto, versiegeltes
Transkript mit Grenzen, Fachwörter und Skalen mit Paritätstests.

Rollout: Ein Image mit diesem Stand startet in Produktion nur mit
VOICE_ENCRYPTION_KEY in apicore-backend-secret (ARCHITECTURE Annahme 22).

Gates: Backend tsc, eslint, 922 Unit-Tests, e2e 100 Suites / 1004 Tests.
