feat: add Delta Dental Individual (DeltaIndiv) eligibility check flow; fix CCA eligibility false-positive error

CCA step1 was treating the harmless "password set to expire" banner as a
fatal error, closing the browser before the eligibility popup/report
could be captured. Now it short-circuits to success once the patient
popup renders and ignores password-expiration notices.
