fix(editor): NPC + object position/rotation NaN guards on JSON load

Browse source 
Mirrors the recent scale guards. NaN/inf positions or rotations make
the M2 renderer's matrix math produce chaos-shaped instances or crash
during normal computation. Now both fields are reset to zero on load
when any component is non-finite.
