-- WooCommerce store connections: per-company WooCommerce REST API credentials
-- for the order/refund transaction feed (extensions/general/woocommerce).
--
-- Unlike Stripe Connect there is no platform account: WooCommerce hands each
-- connected app a per-store consumer key/secret (via the /wc-auth/v1/authorize
-- handshake or manual key entry). Both are secrets, so they are stored
-- AES-256-GCM encrypted with a dedicated server-side key
-- (WOOCOMMERCE_CREDENTIALS_ENCRYPTION_KEY), never in plaintext. The encrypted
-- blobs are useless without that env key, mirroring the Skatteverket token
-- store.
--
-- Modeled on stripe_connections (20260712100000): same status lifecycle, same
-- member-scoped RLS, no DELETE policy (connections are revoked, never deleted,
-- for audit). Like stripe_connections there is no write_audit_log trigger:
-- this is connection state, not accounting data, and audit-logging rows that
-- carry encrypted credentials would copy secret ciphertext into audit_log.
