Fix zoom issue during copy paste in clipboard example

[arunjose696]

Copy and paste no longer tries to autoscale the image. The image is always copied and pasted at 100% zoom.

The purpose of this change is to:

1. Fix an issue in the clipboard example where the pasted image had different zoom levels across monitors
2. Remove all calls to DPIUtil.get[Native]DeviceZoom()

Previously, when copying an image in the clipboard example, the image at the current zoom level was stored to clipboard using getImageDataAtCurrentZoom(). However, in normal Windows behavior (e.g., Paint), images are always copied at their original size regardless of the current zoom. When pasting, the image is pasted at 100% zoom, and the application handles zoom internally when displaying the image.

To match this behavior, copy and paste now always handle images at 100% scale, ignoring the current zoom and leaving zoom handling to the image class when it is fetched for display.
