Fix payment method handling for non-default types (apple_pay, google_pay)

Yoco webhook payments are tagged with whatever wallet type the gateway
reports, not just cash/card/eft/voucher. Cashup/report totals were
silently dropping those into the "other" bucket instead of "card", and
the new user payment history page couldn't filter by them and showed
raw snake_case values.
