Issue Description: Implement integration tests for Fleet Manager API v2 for processor CRUD operations.

Acceptance Criteria: The processor API v2 integration tests are implemented

Out of Scope: The tests do not need to pass, given the functionality might not be ready yet.

Additional Information: The idea is to develop the integration tests in accordance with the actual processor API v2 implementation providing a sort of test-driven development approach. Feel free to split this task into a series of tasks based on the actual needs.
