### Description

I use https://github.com/dnut/clipboard-sync for clipboard synchronization
In previous versions of DMS, I could use it normally to copy images and paste them into other programs
However, since the major DMS update, when I copy images from it, the result of pasting is the image path rather than the actual image content
such as `/home/***/.cache/dms/clipboard/1771929277015094128.png`

### Expected Behavior

Expected to paste normally the actual image content

### Steps to Reproduce

1. Enable clipboard-sync service
2. Copy an image/take a screenshot
3. Select the image from clipboard manager
4. Paste the image in other programs
5. Getting incorrect path output

### Error Messages/Logs

_No response_

### Screenshots/Recordings

_No response_

Reproduce the issue with dnut/clipboard-sync enabled: copy or take a screenshot, select it from the DMS clipboard manager, and paste into another program. Compare whether the target receives the image content or the cached PNG path. Done means image selections paste as images rather than paths.
