Reject records in Farajaland and end-to-end test rejection

[naftis]

Description

Let's create a light-hearted check, that when the child's name is President, the birth gets rejected because no one should get born into leadership positions in Farajaland :) This is to test if the country config can actually use the rejectRegistration endpoint in Gateway

Acceptance criteria

GIVEN a birth registration is made in Farajaland
WHEN the child's name is President
THEN the birth gets rejected via rejectRegistration endpoint

Dev tasks

• In Farajaland, add a check in the event-registration endpoint if the child's first name is President, the birth gets rejected via the rejectRegistration endpoint
• Create a E2E test that checks the registration actually goes to the rejected workqueue
