Root-Cause: Frontend-Komponenten (SignatureManager, LabelManager) rufen Endpunkte auf die das Backend nie hatte (404/405 in Production). Anders als ai/sessions sind diese Funktionen ECHT in Komponenten eingebunden -> Backend-Routen nachbestellt statt Frontend-Calls zu loeschen:
(1) PATCH+DELETE /mail/signatures/{id}: MailSignatureUpdate-Schema neu, Tenant-Scoped + Owner-Check (403 bei fremder Signatur), is_default-Exklusivitaet beim Setzen. (2) DELETE /mail/labels/{id}: gleicher Stil. (3) updateDraft Frontend: apiPatch -> apiPut (Backend hat PUT /drafts/{id} bereits). Beweistest tests/test_mail_sig_label_routes.py 5/5 gruen (PATCH-Werte, DELETE+Liste-leer, 404-Faelle).
Verifikation: create_app registriert beide neuen Routen (563 total); ruff clean; tsc exit=0.
