Ask Flex Auth list, not read, for each overview row (INFD-WP-0004-T03)

The overview now requests the new list action and its rows carry only the
memo id, version, question, live approval status and the person's own
responses without notes. Opening a memo still asks read; every act asks
its own action. The fixture Flex Auth package admits list under a
re-derived pin. Not deployable until flex-auth answers INFD-IN-0008.
