feat(website): default cloud-nodes sort to most-installed

Adds a 'Most installed' sort option (downloads desc) and uses it as
the default. The packs in the snapshot already carry registry-served
download counts so the index now leads with what the community uses
most. Custom-styled chevron with extra right-padding (pr-12) so the
text never crowds the dropdown indicator.
