Add copy-settings button for Icon location/rotations

[rayanth]

Describe the solution you'd like Would like a "Copy settings" button in the Icon Render section of SEUT that copies the Zoom/Distance/Location/Rotation settings to other scenes in the file.

Describe alternatives you've considered Currently the only way to copy these settings is to duplicate the scene, which can lead to other frustrations.

This should be implemented as a separate button so that you can avoid overriding the orientation if you just want to update the export settings.
