ci: fix existing tests based off new permission handling

- Renamed test cases to reflect changes in permission checks being handled at the route level.
- Updated assertions to verify that agents are returned regardless of user permissions due to the new permission system.
- Adjusted mocks in AppService and PermissionService tests to ensure proper functionality without relying on actual implementations.
