Fix unreadable white-on-white text when hovering the active identity page tab

The JS toggle set bg-white/text-ink on the newly active tab but never
removed hover:text-white, which was still sitting in that tab's class
list from its inactive state (or, for Identity, added by hovering
while active) -- hovering the active pill turned its own text white
on its own white background.
