Audited every place Payment.method reaches the UI. The main user
dashboard's per-registration payment list (fed by GET
/api/payments/registration/:id) was still showing the raw gateway
string, since that endpoint is shared with the staff-facing supervisor
payments page and wasn't touched by the earlier /mypayments fix.
Extracted the cash/card/eft/voucher/other normalization (matching
normalizeUserMethod on the backend) into frontend/src/lib/paymentMethod.ts
and applied it to both user-facing payment displays. Staff-facing views
(supervisor payments, at-the-door, reports, cashup) intentionally keep
showing the raw method for reconciliation and were left unchanged.
