Add "Transfer" as a Refund Reason

🔍 Problem Statement

Currently, Pelcro provides a predefined list of refund reasons, but it does not include "Transfer". As a result, when funds are refunded as part of an internal transfer (e.g., moving funds between accounts), users must select an inaccurate reason such as "Requested by Customer." This creates discrepancies in accounting records, reporting, and audit trails by misrepresenting the actual purpose of the refund.

💡 User Story

I want to select "Transfer" as the refund reason when issuing refunds related to internal fund transfers,
So that refund records accurately reflect the purpose of the transaction and accounting records remain consistent.

🎯 Definition of Done (DoD)

✔ Add "Transfer" as a selectable refund reason when issuing refunds.

✔ Refunds marked as "Transfer" are saved and displayed consistently across the dashboard, reports and exports.
