[PCB Editor] Move Corner To... does not use defined grid origin

Description

In the PCB Editor, when a grid origin is set and you are trying to move the positions of the corners or midpoints of fill zone lines using "Move Corner To...", the dialog box doesn't use coordinates relative to the configured grid origin point. It uses the default global origin point instead.

It should be using the grid origin point as its reference origin.

Steps to reproduce

1. Preferences -> Preferences -> PCB Editor -> Origins & Axes -> Display Origin = Grid Origin
2. Place -> Grid Origin (Place anywhere other than the original default origin.)
3. Place -> Add Filled Zone (Draw a rectangle somewhere.)
4. Right click on one of the corner points of the fill zone polygon -> Shape Modification -> Move Corner To...
5. Enter coordinates based off the grid origin placed in step number 1.
6. Click OK and noticed that the coordinates used are not based on the origin placed in step 1.
