fix(a11y): enlarge mood tag chips to the 44px tap target

The structured-tag picker chips and the side-effect chips sat at 32px
(min-h-8), under the 44px minimum and a fat-finger risk on a phone where
they wrap tightly. Bump both to min-h-11 with matched padding so the tap
target clears 44px without loosening the visual density.
