Panels poliert: Ebenenkombi in Oberleiste, Satelliten-Dialoge, Caps weg, Perf

- Ebenenkombination raus aus Ebenen-Panel, in Oberleiste-Topbar +
  Editor-Satellite (AusschnittLayerDialog embedded). doc.Strings
  haelt active_comb_name, auto-clear bei manueller Eye/Lock-Aenderung.
- EbenenSettingsDialog jetzt Satellite mit Ebene-Picker-Dropdown
  (auto-save on switch via SAVE_KEEP).
- Per-Ausschnitt Einstellungen-Satellite (Massstab, Display, Overrides,
  Ebenenkombi). Alte 'Sichtbarkeit bearbeiten'-Option entfernt.
- Layouts/Ausschnitte: Top-Header weg, Sticky-Footer mit Anzahl +
  Aktionen. LayoutDialog ist jetzt Satellite mit Format-Live-Preview.
- Panel-Captions + Default-Ebenen-Namen auf Mixed-Case (Ausschnitte,
  Ebenen, Waende ...). Nur DOSSIER bleibt caps.
- DimensionenApp: Card-Optik raus, REF-Wuerfel mit Kreisen statt
  Quadraten + Hover-Scale.
- GeschossManager angeglichen an EbenenManager: Rechtsklick-Menue,
  Lock-Button, Delete-X, Duplizieren. layer_builder honoriert z.locked.
- Active Sublayer folgt jetzt dem Geschoss-Wechsel (gleicher Code
  unter neuem Parent).

Performance Geschoss-Wechsel:
- elemente._send_state() ersetzt durch _notify_active_geschoss()
  (Partial-Push statt 200+ Elements re-enumerieren).
- _apply_visibility dedupe via sticky last-applied-signature
  (STATE_SYNC-Echo loopt nicht mehr durch alle Layer).
- _update_clipping nur wenn alt oder neu hasClipping=True.
- Redundante doc.Views.Redraw() im CPlane-Pfad entfernt — die folgende
  apply_visibility-Roundtrip redrawt 30ms spaeter ohnehin.
