Frontend: Voice-Umzug in Desktop-App, MC3-Prototyp, UI-Rework-Dateien auf lucy-v2, dist konsistent

- VoiceView + components/voice + lib/voice entfernt (lebt jetzt in client/lucy-desktop)
- mc3/: Basisstation-Prototyp hinter #mc3-Weiche (non-destruktiv)
- roleMeta/useLucyHealth/useExpertMode/ExpertToggle/LucyHealthCard/WarmSetManager (UI-Rework, auf main a341d25 committet, hier nachgezogen)
- dist frisch gebaut (Asset-Stand war inkonsistent: alte geloescht, neue untracked)
