Claude 58e4bbff49 fix(editor): a model turned with the gizmo about the vertical axis no longer jumps back and forth ...

The angles of the whole gizmo matrix were decomposed every frame and the model was turned by their difference from its own.
The decomposition gives the angle about the vertical axis only within -90..90 degrees: past 90 it comes out as 180 - angle
with the other two axes turned by 180, so a drag one way turned the model back and flipped it. The turn is now taken from
the delta matrix of this frame (small, so its angles decompose with no ambiguity) and wrapped to -180..180.
