feat: Camo/Height/Emission-Slider nicht mehr persistieren

Die 8 HUD-Slider (Half Lambert, Brightness, Saturation, Specular Damp,
Occlusion Threshold, Normal/Parallax/Emission Intensity) als
[NonSerialized] markiert: bleiben zur Laufzeit ueber Respawn erhalten,
werden aber nicht mehr im PaintHud.json gespeichert/geladen. Tote
hasCamoValues/hasHeightValues-Flags entfernt.
