Switch knob sat 7px off the edge: no preflight left the browser's button padding on ReUI buttons

button[data-slot] gets padding 0 in the base layer (ReUI size utilities and the
console's own styles still win). The switch's help now lines up under its label by
the switch's 32px, and the dead .toggle input CSS from the native-switch days is gone.
