-- Per-store webshop booking settings: payment-method -> account mapping that
-- prefills the order booking dialog (prefill only; the user always confirms,
-- and per-booking overrides persist only via the explicit "remember" opt-in).
--
-- Keyed by (company_id, platform, store_scope) rather than hung off
-- woocommerce_connections: the core booking route must read it without
-- touching extension-owned connection state, the mapping must survive
-- disconnect/reconnect (connections are revoked, never deleted, and can be
-- re-created), and Shopify reuses it with zero schema change.
