feat(reputation): surface 'payment proof' as its own tier, never as verified

The proof tag is self-reported and unverifiable client-side, so it must not read
as proof of payment. useTradeReputation now exposes withPaymentProof (mutual
trades carrying a proof), shown on TradeReputationCard as 'with payment proof
(self-reported - not verified)' distinct from the verified count.
