MHR UI - ToD| Include refund statement in rejection notice PDF

### Background
A requirement was identified for the rejection notice PDF to include a clear statement indicating that a refund has been processed when a filing is declined. During the discussion, the need for the client to understand the connection between the original payment and the refund was emphasized. It was also noted that staff must be able to rely on the notice to confirm that the refund information reaches the client. The PDF was described as the primary communication channel for rejected filings, and the inclusion of refund details was viewed as essential to avoid uncertainty for both clients and staff.

### Risks

- Clients may be unaware that a refund was issued if the information is not included, which may lead to unnecessary inquiries.
- Staff may face increased follow up work if clients question the refund status due to unclear notices.
- Missing or incorrect refund statements may create records that do not reflect actual payment outcomes.
- Formatting errors may cause the refund message to be misplaced or omitted, reducing the reliability of the notice.
