When user role in Atlas doesn't allow to make any changes to the data in UI, we connect them to the database with correct access roles, but the UI is still showing the editing UI. User can try to modify the documents, but the request corretly fails with "not allowed" error

We can make this expirience better by mapping Atlas user role to compass preferences readonly mode which hides those UI elements and so doesn't expose users to the feature they don't have access to.

Specifically we'd want

• Read only Cloud users to be Compass read only everywhere
• Read write Cloud users to be read only on the indexes page

Also, add an E2E test to verify that this works.
