Tests

add replyTo and X-Formsg-Submission-ID headers to MRF outcome emails (#9570) (#9570)

TC1: Workflow completion email includes correct headers

• Set up an MRF form with at least one email field across multiple steps and complete the full workflow
• Capture the outgoing completion email (e.g. via Mailtrap or email header inspection)
• Verify that the Reply-To header is present and contains all email field answers from all steps, comma-separated
• Verify that the X-Formsg-Submission-ID header is present and matches the submission ID

TC2: No email fields — headers degrade gracefully

• Set up an MRF form with no email fields and complete the workflow
• Verify that the completion/approval email is sent without a Reply-To header (no empty header)
• Verify that the X-Formsg-Submission-ID header is still present
