Counts in the filter panel chips (base models, tags, model types), the All Types
dropdown and the Refresh scope rows were rendered as raw digits, so a library with
10k+ models turned every chip into a five digit pill that dominated the row it sat
in — and the Refresh menu grouped its numbers while the filter panel did not.
One formatter now renders all of them (`formatCount`): exact and locale-grouped
below 10,000, abbreviated to three significant digits above it, and abbreviated
only where the locale's Intl compact form is a real unit and narrower than the
plain number — German keeps 18.475 instead of the rounded 18.500, Russian keeps
18 475 instead of the wider 18,5 тыс.
Their hover text is always present and always exact ({name} — {count} models, and
... recipes on the Recipes page): an affordance that only exists above a threshold
is undiscoverable, and the tooltip is also what reveals a chip label that CSS has
ellipsized.
Chips gain a two-slot layout (the name ellipsizes, the count keeps a tabular
right-aligned slot) so a long tag name can no longer push the count out of the
chip; Refresh rows move from float:right to a flex row, which keeps the counts in
a right-hand column and lets a long root label ellipsize. The All Types group
tooltip moves onto its trigger so it stops leaking onto the menu options.
The two new strings ship as [TODO: Translate] placeholders in the nine locales;
the translation pass is the next commit.
