[Bug] Zone entities are all located at 0,0 and unexpectedly selectable on the GM screen

All Zone entities are located at coordinates 0,0 regardless of where their points are located or rendered. The GM screen can unexpectedly select the entity location at 0,0 and move it, which moves the offset zone points.

there seems to be at least some buggy/unintentional behavior. Here I am just doing a small rectangular selection (as I often do for single objects, as it is more reliable than clicking), but somehow selecting a whole array of zones

@GinjaNinja32:

zones don't get their transform.position set to COM like they did on legacy, so they're all at the origin with a really big offset in their polygon points

@daid:

Dont think there was a technical reason beyond "this was easier"

Start by tracing how Zone entities set transform.position and store their polygon points, then inspect how the GM screen uses entity locations for selection and movement. Verify the fix by confirming zones are positioned at their center of mass rather than 0,0 and that selecting or moving them no longer applies an unintended offset to their points.
