Shopify permissions

Write scopes are checked again for the exact store before execution and rollback.

1. 1.Review the requested read and write scopes during connection.
2. 2.Shopify permissions are approved together during installation. Existing stores approve updated access when reopening Glimmio in Shopify.
3. 3.Do not share one store credential across unrelated business accounts.
4. 4.A missing scope must block the mutation rather than degrade into a partial write.
