Drop padded count from limited landing session counter

The padStart was added so a centered title wouldn't shift width as
the count ticks during loading, but the limited-tier landing panel
is left-aligned — the padding just shows up as a visible leading
indent that misaligns the line with the model name and CTA above
and below it.
