根因(购买按钮全端「点了没反应」):
- 生产 pay-v2 的 CNY 渠道是哪吒(nezha)聚合(底层支付宝/微信),客户端却给
  CNY 发 method=alipay → pay 不认 → POST /api/v2/orders 400。USDT/crypto 一直正常。
- 且 _buy 只在 awaitingPayment 时导航,下单失败(phase=failed)既不导航也不弹错,
  非 Auth 异常还直接从 start() 抛出未捕获 → 用户看着「没反应」。

改:
- PayChannelX.method:cny 'alipay' → 'nezha'(usdt 仍 crypto)
- payment_provider._metadata 法币条件同步 nezha;start() 补 catch(_) 兜非 Auth 异常
  落 failed(状态机不再卡 creating)
- purchase_page._buy:phase==failed 时 showPangolinToast 显式提示
- payment_page 换支付方式的另一渠道 alipay → nezha
- 测试钉:PayChannel.cny.method == 'nezha'(发错 method 会被 pay 400)

nezha 返回 render_type=redirect(payload.url),客户端现成 redirect 分支直接接;
orders_page 早有 'nezha'→payMethodNezha 标签。服务端无需改(method 透传、
SettlementCurrency 只区分 crypto vs 法币)。

验证:flutter analyze 干净;payment 相关 18 测试全过。
