refactor: Moved authorizer logic into use cases from services

[m-t-a97]

• This allows internal systems to be able to call services without being blocked by permissions due to the authorizer.
• Authorizer is now in the usecase layer which is used by the handler and also by plugins in library mode which enforces authorization.
• Improves code architecture, scalability and maintainability.
• Removed organization create and list permissions allowing any user to create an organization and list their own organizations (previously this was completely blocked and unnecessarily required permissions to do this which doesn't make sense).
• Removed create permission on API keys for users so now any user can create their own API keys without requiring a permission to do so.
• Renamed GetAllOrganizations method to GetOrganizationsByOwner.
