Allow unverified users to create a clinic

Since email verification is no longer enforced at sign-in, gating
organization creation on `user.emailVerified` blocked onboarding with
"You are not allowed to create a new organization". Allow any signed-in
user to create a clinic; re-tie to emailVerified when verification returns.
