The browser cache policy never is too broad. It prevents the browser from caching image thumbnails in the Assets app and preview images in the asset chooser. Users may experience this as slow performance. The browser reloads thumbnails every time the user expands/collapses an asset folder, which causes delay and feels frustrating.

To reproduce:

1. Go to https://demo.magnolia-cms.com/
2. Open the Assets app.
3. Expand the /tours folder. Image thumbnails are generated and loaded.
4. Collapse and expand the folder again. Image thumbnails are loaded again.

The never policy configuration was introduced Magnolia 5.5.1 (MGNLCACHE-12). The purpose was to address an issue (MGNLUI-3769) where a user adds an image in CKEditor, then crops the image in Assets, but doesn't see the edit reflected in CKEditor.

Proposal: Remove the never policy and introduce a more specific policy
CKEditor issue should be solved without impacting image thumbnails and previews in the Assets app, see MGNLUI-3769.
