fix(medications): bump phase-config-dialog Input + Button to 44 px on mobile

The duration Input and the MIN/% toggle Button were both `h-8` (32 px,
below WCAG 2.5.5) and the Input pinned `text-sm` which defeated the
`Input` primitive's iOS-zoom defence (`text-base md:text-sm`).
Drop the size override on the Input and bump both heights to
`h-11 sm:h-9` so phones get a 44 px target while desktop keeps the
dense row.
