style(type): correct the trigger text from 16px back to the view-switcher's real 14px

The earlier bump measured the view-switcher's BUTTON (16px, inherited) instead of its visible
label span (text-sm = 14px), and 14px is the size the user actually finds comfortable. Walk the
over-sized triggers back to text-sm: FilterSelect, SortControl, ViewSwitcher, and the Combobox
input (which was 14px before the bump anyway). The secondary text already at text-sm/text-xs
(count, chips, widget headers, section labels) was correct and stays.
