Maintaining the positioning of the files from v2 to reduce cognitive
load.
Indentation of yaml files now matches `.editorconfig`.
All mock files regenerated.
Added empty `{}` following convention from `mockery init` etc.
Removed directory specification where it would already match.
* Fix mockery setup for graph service
Add missing interfaces to .mockery.yaml. Use existing mocks from protogen
where possible. Remove remaining //go:generate call.
* Add mockery config for settings service
* Add mockery config for proxy service
This moves the lookup and the creation of the users' role assignemt out
of the user backend into its own interface. This makes the user backend
a bit simpler and allows to provide different implemenation for the user
role assignment more easily.
