viewer/command: add item download button

Fixed a reactivity issue with props used in a composition function (useItemResource)
Fixed crash with null items in LayoutTop
Changed how downloadable items are identified: We use the fact they are materialized in the gallery instead of a hardly defined "listing condition". This also simplifies the code.
