Fix edit permissions only checking the root permission

[woodwoerk]

Description

Update the permissions handling logic to check if the user has edit permissions for the selected plan. Previously (in staging, not production) we incorrectly checked the edit permissions on the root NZC framework, which was only true for superusers.
