Use preview downscaling in fewer places (#9678)

Thumbnail downscaling is currently being used in more places than it
should be.
- Nodes which display images will display incorrect resolution
indicators
<img width="255" height="372" alt="image"
src="https://github.com/user-attachments/assets/674790b6-04c8-4db0-84c2-2fa2dbaf123d"
/> <img width="255" height="372" alt="image"
src="https://github.com/user-attachments/assets/1dbe751b-7462-4408-9236-9446b005f5fc"
/>

This is particularly confusing with output nodes, which claim the output
is not of the intended resolution
- The "Download Image" and "Open Image" context menu actions will
incorrectly download the downscaled thumbnail.
- The assets panel will incorrectly display the thumbnail resolution as
the resolution of the output
- The lightbox (zoom) of an image will incorrectly display a downscaled
thumbnail.

This PR is a quick workaround to staunch the major problems
- Nodes always display full previews.
- Resolution downscaling is applied on the assert card, not on the
assetItem itself
- Due to implementation, this means that asset cards will still
incorrectly show the resolution of the thumbnail instead of the size of
the full image.
