fix(widgets): fix downloads widget and add SSR prefetch

Remove WidgetEmptyState guard from downloads (widget renders fine with
empty data). Fix columnsSort filter logic from .some() to .every() so
non-sortable columns are correctly excluded. Add server-side prefetch
via tRPC caller so download data is available immediately on page load.
