The endpoint is already defined in the openapi.yaml file and has a default implementation that returns a 501 Not Implemented.

Implement the API such that:

• It is secured using the support and test security roles (should use an API key via the x-rh-swatch-psk header).
• It uses the outbox repository the outbox repository to update an existing outbox record based on the outbox DTO JSON in the request body.

Required Testing

• Unit tests & Junit integration test using test containers.
• Existing IQE component test is updated:
  • Rename the test to test_update_outbox_record
  • Use the POST endpoint to create initial record.
  • Use the GET endpoint from SWATCH-3779 to verify data.
• Tests are added to validate that the endpoint is secured appropriately for each role.
• Thought has been given to any other negative test cases that might be out of scope of this card, and are documented somewhere.

Acceptance Criteria

• The endpoint can be used to update an existing outbox record.
• Adequate test coverage exists.
