post https://sandbox.finmid.com/api/v1/capital/simulation/businesses//onboardings/latest/reject
This endpoint simulates rejecting the latest onboarding, transitioning it to REJECTED state.
If onboarding hasn't been submitted yet, this API will also simulate submit action.
In the live environment, this would happen when the Business fails verification checks or
does not have sufficient financials to receive an offer.
Only available in sandbox environment.
