List back-filing request options

List the registrations and open periods eligible for a customer back-filing request, across every organization your credential owns; send an `Organization-Id` selector to narrow to one. An organization with nothing eligible contributes no registrations rather than failing the read.

Category: Filings

registrations (BackFilingRequestRegistrationOption[]) - Registrations with open back-filing periods across the scope.
