/**
 * GET /api/extensions/woocommerce/orders/cron
 * Nightly order sync for connections that opted in (transaction_sync_enabled):
 * imports each connected store's paid orders and refunds into the
 * transactions inbox as a bank-style feed on the 1680 cash account.
 *
 * Read-only against the stores, and it never posts to the journal: rows land
 * unbooked; booking stays a human decision. Idempotent via the
 * (company_id, external_id) unique index, so overlapping windows and re-runs
 * are no-ops. Emits no events, so no ensureInitialized() is needed.
