Kamera-Panel + Iso-Button in der Oberleiste

Oberleiste:
- View-Gruppe: Iso-Button neu zwischen Right und Persp
- matchView: Iso = parallel ohne orthogonalen Standard-Namen,
  Perspektive = !parallel — beide via Projektions-Flag unterschieden
  (Rhino-Viewport-Name ist oft "Perspective" fuer beide)
- Camera-Knopf (Icon: videocam) oeffnet das neue Kamera-Panel
- SET_VIEW Backend: 'Iso' faelltt auf kamera._set_iso(vp, "NE")
- OPEN_KAMERA_PANEL Handler

Kamera-Panel (neu — rhino/kamera.py + src/KameraApp.jsx):
- Viewport-Name + Projektions-Toggle (Persp/Parallel)
- 4 Iso-Quick-Buttons (NW/NE/SE/SW) — true-iso 35°/45°,
  Kamera-Distanz auto aus Szenen-BBox
- Vec3-Felder fuer Kamera-Position + Blick-Ziel (numerisch
  editierbar, m)
- Distanz read-only
- Brennweite (mm) bei Persp, Frustum-Breite (m) bei Parallel
- Zoom-Extents-Button
- Presets: speichern + anwenden + loeschen, persistiert in
  doc.Strings["dossier_kamera_presets"] (JSON)
- Eto-Form-Satelliten-Fenster (420x600) via panel_base.open_satellite_window
