fix: open previewable assets from list preview click/double-click (#9077)

## Summary
- emit `preview-click` from `AssetsListItem` when clicking the preview
tile
- wire assets sidebar rows and queue job-history rows so preview-tile
click and row double-click open the viewer/gallery
- gate job-history preview opening by `taskRef.previewOutput` (not
`iconImageUrl`) and use preview output URL/type so video previews are
supported
- add/extend tests for preview click and double-click behavior in assets
list and job history
