swarm-ui: disable the wanted-toggle badge on a destroyed row

argus, review: the primary wanted-toggle badge still had no
wanted === "destroyed" guard, so it stayed clickable on a destroyed
row and would PUT {state: "up"} on click -- directly contradicting
the destroy confirm dialogs own "not reversible from here" copy.
Missed this in the previous fix-up (which only addressed the
ConfirmDialog-for-stop ask). Added the guard to both the click handler
and disabled, plus a title explaining why on a destroyed row.
