refactor: make toolbar wrap instead of scroll, fix overflow

Use flex-wrap instead of overflow-x-auto for the formatting toolbar —
scrolling clips absolutely-positioned dropdown popovers (CSS forces
both axes to auto). All buttons are now always visible, wrapping to a
second line on narrow screens. Remove the More dropdown entirely since
all items are top-level. Add overflow-hidden to the editor card to
prevent horizontal overflow.
