Fix oversized toggle switches on mobile

The global @media (pointer: coarse) rule was forcing min-height: 44px on
toggle button elements, inflating them from 20px to 44px. Added
data-slot="toggle" to all 10 toggle buttons and a CSS override to reset
their min-height, keeping the parent row as the touch target.
