fix: the membership status vocabulary moves beside Membership, so the Patreon client never imports the roster

240f11c made PatreonClient._membership import has_paid_access from membership_roster. test_gated_reason::test_no_fetch_path_can_read_the_roster failed on it, correctly: native_ingest_common is a fetch root, patreon_client is reachable from it, and no fetch path may be able to reach the roster. The roster is allowed to explain a skip, never to cause one.

MEMBERSHIP_STATUS and has_paid_access are pure platform knowledge with no database behind them. They move to native_ingest_common, next to the Membership type they interpret (the same move C7 made for Membership itself). membership_roster, membership_reconcile, patreon_client and the tests import them from there. There is no re-export from membership_roster.

The guard is unchanged. The lapsed-orphan skip from 240f11c stays as it was.
