feat(999.58-03): repoint demoTutorialDialog off the scene dialog accessors

- Drop getStageSettings()->updateFromStage() (3 sites), getMaterialSettings()
  ->updateDefaultMaterialsFromStage(), and LightSettings::getInstance(0)
  ->updateFromStage() (2 sites) — dialog-widget refreshes with no target now
- Preserve all surrounding Stage mutations (clearLightSources/addLightSource,
  setBackgroundColor, Stage::Material writes) + the applyPreferences() calls
  that carry the actual render effect via the Inspector controllers
- Drop the now-unused lightSettings.h/stageSettings.h includes
- All sites are inside #ifdef BALL_HAS_RTFACT (dormant this era); RTfact path
  stays compilable for a future re-enablement
