The key changes made in this code include the addition of a Super Admin layout. Also, subscription functionalities are updated and optimized. This ensures read, write permissions are specific to the relevant user and a helper function has been implemented to check if an account has an active subscription. Furthermore, UI enhancements have been made to the accounts table in the administration section. The seed data has also been modified.
Added comprehensive tests for the functionality of creating, updating, and verifying billing orders and subscriptions in the Supabase database. Tests now ensure appropriate behavior of upsert operations, validation of inserted or updated data, and proper calculation of derived fields. This contributes to better coverage and confidence in the production-ready status of these features.
