Benachrichtigungen: Web Push und E-Mail als Kanaele der Automatiken
Neuer BenachrichtigungTransport hinter der Aktor-URL "Benachrichtigung": push schickt an alle angemeldeten Geraete (homeMesh.push_abos), mail ueber den SMTP-Zugang aus der config.ini. Ein Abo, das der Push-Dienst mit 404 oder 410 ablehnt, wird geloescht statt weiter angeschrieben. Daneben hoert der Runner auf benachrichtigung/# - darueber schickt die Probe aus den Einstellungen, ohne dass die Weboberflaeche verschluesseln muesste. Zugestellt wird im Haupttakt, nicht im MQTT-Faden. pywebpush, py_vapid und http_ece liegen wie die uebrigen Fremdpakete im Ordner, nicht in site-packages; transports.py haengt ihn an den Suchpfad. Das Schluesselpaar erzeugt vapid_erzeugen.py und bleibt ausserhalb des Git. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
