Search typeahead: show total found count in the dropdown

The /search/suggest endpoint now returns { items, total } — each filtered query
is reused for both the Take(5) preview and a CountAsync — and the dropdown's
footer link reads «مشاهده همه N نتیجه برای «q»» (Persian digits) instead of a
bare «همه نتایج». The /Search page already showed counts.
