Wide tables stretched the whole page because the shell's main is a flex
item without min-width:0 and no table had a scroll container, so the
header and the summary tiles scrolled out of view. Every table now
scrolls inside its own overflow-x-auto container, the sidebar no longer
shrinks, and long CVE ids, versions, targets and image references are
kept on one line or truncated with a title tooltip.
