feat: 支付渠道每日限额(渠道维度全平台统计)
- config.ts:新增 MAX_DAILY_AMOUNT_ALIPAY/WXPAY/STRIPE(默认 alipay/wxpay 各 1w,stripe 不限) - lib/order/limits.ts:getMethodDailyLimit + queryMethodLimits 共用工具,支持动态渠道兜底 - order/service.ts:createOrder 校验渠道限额,超限抛 METHOD_DAILY_LIMIT_EXCEEDED - api/limits/route.ts:公开接口 GET /api/limits,返回各渠道今日用量/剩余/是否可用 - api/user/route.ts:config 响应中加入 methodLimits,前端一次请求即可获取限额状态 - PaymentForm.tsx:额度已满的渠道置灰 + 标注「今日额度已满」,无法选择 - pay/page.tsx:AppConfig 加 methodLimits,传给 PaymentForm,新增错误码映射
