fix(web): stale adaptive image when original overlays preview (#27621)
AdaptiveImage stacks quality layers (thumbnail → preview → original) as they load. Without compositor layer promotion on the container, the browser could render a stale frame when the original-quality layer was overlaid on top of the preview-quality layer.

Add `will-change: transform` as a class on AdaptiveImage's root element so it gets a dedicated compositor layer from first paint. This also subsumes the imperative `style.willChange = 'transform'` that zoomImageAction was applying to the same element (the zoom target from photo-viewer is the AdaptiveImage root), so drop that now-redundant code.
