console.require_2fa exempted admin.settings from the redirect it forces on
an unconfirmed operator, but that page only ever configured the global
policy — nobody could enrol behind it. A newly invited operator stayed
permanently redirected to a page with no way to satisfy the requirement,
the opposite of what the switch was for.
Adds enable/confirm/regenerate/disable to Admin\Settings, reusing Fortify's
own actions exactly as the portal's Settings already does — they only ever
touch the model they're handed, no guard or auth() call inside them, so
pointing ConfirmsPassword's guard at 'operator' is the only change needed.
The new card is deliberately not gated behind the site.manage capability
that hides the rest of this page's Owner-only sections: the compulsory
switch applies to every operator, so enrolment has to be reachable by every
operator too. Dropped the account card's stale hint pointing at a "separate
security area" that never existed.
