Masse-Dropdown in Oberleiste + Satellite-Settings statt Dimensionen-Inline

User-Feedback: Mass-Style passt nicht ins Dimensionen-Panel, und der
Name "Mass-Style" gefaellt nicht. Umzug in die Oberleiste (analog Display)
+ Zahnrad oeffnet eigenes Settings-Fenster. UI-Begriff jetzt "Masse".

Frontend:
- OberleisteApp: neue Gruppe "Masse" mit Preset-Dropdown + Zahnrad-Button
  zwischen Display und Massstab
- MasseSettingsApp.jsx (neu): Satellite-Fenster mit Name/Raum-Rundung/
  Mass-Dezimalstellen/Mass-Einheit + Picker + Add/Delete
- DimensionenApp: MassStyleSection raus
- rhinoBridge: setMasseActive + openMasseSettings (Topbar);
  masseSetActive/masseSavePreset/masseDeletePreset (Settings-Fenster)

Backend:
- rhino/masse_settings.py (neu): Bridge fuer das Satellite-Fenster,
  Topics SET_ACTIVE / SAVE / DELETE, triggert regen_all_rooms + topbar refresh
- mass_style.regen_all_rooms(doc): neue cross-modul-Helper, queued
  Raum-Regen fuer alle raum_outline-Objekte
- oberleiste.py: massePresets + masseActiveId im State, SET_MASSE_ACTIVE
  + OPEN_MASSE_SETTINGS handler, Signature update
- dimensionen.py: Mass-Style-Endpoints + State raus (sind jetzt im
  OberleisteBridge bzw. MasseSettingsBridge)
