Input group with dropdown menu selection

<!--
  Расхождение с апстримом: `IconPlaceholder` заменена инлайновым `<svg>`
  (lucide-react v0.545.0 "chevron-down") — см. docs/PORTING.md §5.
  Плавающий слой (`DropdownMenuContent`) не раскрывается в кейсе — см.
  docs/PORTING.md, раздел "непокрытая гейтом площадь".
