Context:
After roles are assignable to collections with OPT-2545 their enforcement needs to be activated.

AT:

• users can only access collections they are authorized to by a role entry for their userId or a group they belong to
• users can only edit a collection (update & delete) if they have the MANAGER role on the collection
• users can only edit collection roles if they have the MANAGER role on the collection
• users can only edit collection scopes if they have the MANAGER role on the collection
• list endpoints (/collection & /entities) only include collections users are authorized to see based on their collection role
• the API indicates the role of the current user on a collection
  • the new field is documented in the wiki
