feat(widgets): redesign gate widgets — readable hierarchy, prominent select-all, styled controls

Titles + intro read as a clear prompt (comfortable line length), options as
spaced choice rows, Other/Back/Exit as discreet secondary controls under a
divider. Multiselect gets a prominent Select all/Deselect all at the head of the
list with a live count.
