feat(ui): simple_table + team_dropdown migrate off antd/@tremor Text

- simple_table: the Tremor Table family is whitelisted in phase 1 so
  only the @tremor Text wrapper was swapped for a plain span with
  semantic text-muted-foreground. File keeps its inline eslint-disable
  for the preserved Tremor table primitives.
- team_dropdown: antd Select with infinite scroll + debounced remote
  search + antd LoadingOutlined \u2192 shadcn Popover + Button (combobox)
  + Input + lucide Loader2/ChevronsUpDown/X. Infinite-scroll is
  driven by the list element's scroll handler with the same 0.8
  threshold. Cleared button spans stopPropagation to prevent the
  popover from toggling open on clear.

Gates: TS \u2713 | Build \u2713.
