improve performance request published and purchased subscriptions

[spielcrypto]

Current behavior

We get all the published and purchased subscriptions and services associated in one

Expected behavior

In the dashboard we should just query the services associated to the subscription once the dropdown of subscription detail is clicked, for it we don't need to delete or update the methods getPublishedSubscriptions and getPurchasedSubscriptions from the Catalog we just need to create new methods inside the account object in it
