fix(ui): respect semver filter when showing latest tag

The 'latest' tag was unconditionally added to visible results even when
it didn't match the active semver filter. This caused versions like 7.6.0
to appear when filtering by ranges like '^7.5 <7.6'.

Keep the original behaviour of always showing latest when no filter is
active (important for incomplete version loads), but respect the filter
when one is active.
