🛠 Summary of changes

• Set the sponsor_id field on in-person enrollments when they are created during the IPP usps location controller update request.
• Updated the enrollment_helper.schedule_in_person_enrollment method to check if a sponsor_id exists on the in-person enrollment before attempting to schedule a usps enrollment.

📜 Testing Plan

Scenario: During EIPP flow when the user submits form for selecting a post office the in-person enrollment is saved with the configured EIPP sponsor_id.

• Login through the oidc sinatra application selecting the Enhanced In-person Proofing level of service.
• Use an exisiting account or create an account
• Continue through the In-person flow until the /verify/document_capture#location page is reached.
• Open the Rails Console
• Verify that no establishing enrollments exist for the current user InPersonEnrollment.where(status: "establishing")
• Search for participating post office and select one
• Verify that the establishing enrollment exists and has the sponsor_id set to the configured EIPP sponsor_id
• Complete the flow and ensure no issues
