fix(editor): syncToTerrain converts world coords back to ADT placement coords

Browse source 
ADT loading converts MDDF/MODF positions from ADT space to render/world
space via core::coords::adtToWorld, but syncToTerrain wrote object
positions back as raw render coords. So saving and reloading would
displace every placed object/WMO, accumulating each save cycle. Now
calls worldToAdt() to round-trip cleanly.
