refactor: make the event-fonts toggle row fully toggleable (a11y)

CodeRabbit nitpick: the whole row (label + switch) now toggles the pref via
Modifier.toggleable(role = Role.Switch); the Switch is visual-only
(onCheckedChange = null) so it doesn't double-fire. Bigger touch target,
one semantics node.
