feat(editor): preserve WMO instance scale across ADT load/save

Browse source 
The MODF scale field (u16 / 1024 = float) is now propagated in both
directions: load reads wp.scale -> obj.scale, syncToTerrain converts
obj.scale * 1024 -> wp.scale (clamped to u16). Combined with the prior
loader/writer changes this means non-1.0 WMO scales (used by some
WotLK content) survive a save/reload cycle.
