Console noise purge: deprecated-API fixes + PixelArtDevControls legacy-Input exception

MenuUi FindAnyObjectByType; GA prefabAssetPath->assetPath x2; Synty sample
FindObjectsByType overload; dead death_b field removed. Real bug caught by
the sweep: the F3 pixel-art toggle used legacy Input.GetKeyDown under
Input System-only handling -> InvalidOperationException every frame in Play.
Suite green (455).
