enlarge the activity-card run-status spinner (T-304)

At size 12 the rotating logo-mark spinner on in-progress collapser cards
read as a static speck. Add a clideIconHero (24) control-geometry token
and use it for ClideStatusIndicator on the collapser — the spinner now
reads as motion at a glance; the success check / error cross share the
size so the card doesn't jump when the run settles. Only call site is the
collapser, so other status surfaces are untouched.
