MC2 Final (D16 c+e): System-Logs mit Fehler-Farben/Filter + Auto-Dedupe

c) System-Logs ausgebaut: neue LogConsole-Komponente färbt Fehler (rot) und
   Warnungen (amber) ein, "Nur Probleme"-Filter mit Zähler, Zeilen-Suche;
   voice-service in die Dienst-Liste aufgenommen (war nur backend-seitig).
e) Mem0-Dubletten automatisch: deterministischer Auto-Dedupe-Loop (täglich,
   apply=True, Schwelle 0.9 > manueller 0.85 da ohne Review) als Backend-
   Hintergrund-Task — kein Memory-Bloat mehr ohne Zutun. Knopf bleibt on-demand.
