feat: Sprachnotizen übernehmen, melden und abschreiben (T7 L2 Tasks 8, 9, 11)

Task 8: POST /inspections nimmt voiceCaptureId; die Notiz wird zuletzt
in derselben Transaktion bestätigt (jeder offene Status, Ruling 1),
Inhalt, Audio und Claim gelöscht; fremde oder geschlossene Notiz 409
VOICE_CAPTURE_GONE, anderes Volk 409 VOICE_CAPTURE_COLONY_MISMATCH;
Wiederholung mit gleichem Schlüssel idempotent.

Task 9: Ereignisse VoiceCaptureReady/VoiceCaptureFailed (nur IDs und
Endcodes), Meldungen „Sprachnotiz für … ist fertig“ bzw. Fehlerhinweis
mit nächstem Schritt, Betreiberhinweis bei abgeschalteter Auswertung;
Handler auch im Worker registriert (sonst gingen die Ereignisse
ungehört durch); keine Weiterleitung an Webhooks.

Task 11: Job voice-transcribe mit Phasen fetch (Audio nur im Speicher
entschlüsselt in ein RAM-Arbeitsverzeichnis 0700/0600) und ingest
(Ergebnis gegen Claim geprüft, Transkript versiegelt, Audio gelöscht,
Auswertung geweckt; Stille/zu lang enden FAILED); Ereignisse genau
einmal in derselben Transaktion. Aufbewahrung: Audio 24 h, Inhalt bis
contentExpiresAt, deaktivierte Besitzer, Zeilen 90 Tage; im täglichen
Cleanup inkl. leerer Job-Läufe (Ruling 10).

Gates: Backend lint, typecheck, 4471 Unit-Tests, build; e2e 103 Suites
(einziger Fehler: Wetter-Test gegen echte API).
