Remove now-dead isContactsHiddenPendingAppleFix kill switch

Contacts was never actually broken by an Apple/OS bug -- it was a
wrong entitlement key in oAI.entitlements, now fixed (abf25bd). No
functional change here: the flag was already false in both places
this session, so behavior is identical; this just removes the
now-pointless beta-badge/conditional-row scaffolding built around it.
