fix(ui-kit): move focus ring to focus-visible on Select/Dialog/Sheet/NavigationMenu

SelectTrigger, DialogPrimitive.Close, SheetPrimitive.Close, and
NavigationMenuTrigger applied their focus ring/highlight on plain focus:,
which also fires on mouse-click focus and leaves a lingering ring/highlight
after every click — unlike button/input/switch/checkbox/toggle/slider and
every other interactive primitive in the kit, which ring on focus-visible:.
Moves only the visible ring/highlight classes to focus-visible: (keeping
focus:outline-none, which correctly clears the native outline on any focus),
with a regression test asserting the corrected class lists.

Closes #8304
