Improve prepaid subscription UX in customer portal

Prepaid subscriptions currently create confusion for customers due to unclear behavior and lack of contextual guidance in the portal. Key issues include: Customers are not clearly informed that cancelling a prepaid subscription does not stop remaining deliveries and does not trigger automatic refunds Prepaid subscriptions are not distinctly labeled (e.g. showing remaining deliveries) Editable fields like delivery frequency can be changed even though they don’t affect already scheduled prepaid deliveries, leading to misleading expectations Portal permissions cannot be configured specifically for prepaid subscriptions A more robust prepaid-specific UX is needed, including clearer labeling, cancellation messaging, and better control over editable fields and permissions.
