c738cfec93 fix(payment): critical audit fixes for security, idempotency and correctness
Backend fixes:
- #1: doSub subscription idempotency via audit log check
- #2: markFailed only when status=RECHARGING (prevents overwriting COMPLETED)
- #3: ExpireTimedOutOrders checks upstream payment before expiring
- #4: Public verify endpoint for payment result page (no auth required)
- #5: EasyPay QueryOrder returns amount, confirmPayment handles zero amount
- #6: WxPay notifyUrl priority: request-first, config-fallback
- #7: EasyPay remove double URL decode in VerifyNotification
- #8: checkPaid/cancelUpstreamPayment use order's provider instance
- #9: Amount NaN/Inf/negative validation in order creation and refund
- #10: Refund amount comparison uses tolerance instead of float64 ==
- #11: Skip balance deduction on retry when previous rollback failed
- #12: checkPaid logs fulfillment errors instead of silently ignoring
- #13: WxPay certSerial added to required config fields

Frontend fixes:
- Payment result page no longer requires authentication
- Public verify API fallback for expired sessions

3c884f8e30 test(payment): add unit tests for payment audit fixes + allow empty supported_types
Tests (1033 new lines, 100% coverage on modified functions):
- amount.go: YuanToFen/FenToYuan with precision edge cases
- wxpay: mapWxState, wxSV, formatPEM, NewWxpay validation
- alipay: isTradeNotExist, NewAlipay validation
- webhook: writeSuccessResponse (wxpay JSON, stripe empty, others text)
- config: validateProviderRequest, isSensitiveConfigField, joinTypes
- fulfillment: resolveRedeemAction idempotency logic

Business logic changes:
- Allow empty supported_types on provider instances
- Block removing payment types when instance has pending orders
- Extract resolveRedeemAction as testable pure function
