-- Zettle parity for every site that enumerates the webshop platforms or the
-- integration connection tables. The zettle extension (20260909100000) adds
-- zettle_connections and writes platform = 'zettle' into webshop_orders, but:
--
--   1. webshop_orders.platform and webshop_store_settings.platform still
--      CHECK (platform in ('woocommerce', 'shopify')), so every Zettle upsert
--      would have been refused at the database (the unit tests mock Supabase
--      and never saw it).
--   2. The writer-role gate trigger (20260902093000) was attached to the
--      shopify/woocommerce connection tables by name; zettle_connections had
--      no aa_enforce_company_writer_role, so a viewer could connect a POS.
--   3. The migration-reset snapshot counts pending/active integrations as a
--      blocker and the reset locks those tables FOR UPDATE (20260818084050);
--      both enumerate stripe/woocommerce/shopify and missed zettle.
--
-- 3 follows the wrapper pattern of 20260826150000 (rename, wrap, revoke)
-- instead of re-issuing the 400-line reset body for one PERFORM line.
