feat(chv): 对齐 Muse P10 支付安全——凭证隔离 + 结账检测 + 每次购买人工审批 + 一次性卡号
- 支付凭证隔离：PaymentCredentialVault（只活内存、白名单
stripe-link/shop-pay、只存不透明 id + 掩码标签、原始卡号
PAN 拒绝入库、按次释放绑定商家/金额/货币、单次 + TTL）
- 结账页检测：detect_checkout（URL + 无障碍树信号，确定性
规则、不读原始 DOM、与 P4 detect_form_risk 同输入形状）
- 每次购买人工审批：PaymentGate 经 P5 对话外通道发审批，
payload 含确切购买详情；完成时先验签、再验详情摘要
（篡改即拒且审批保持待处理）、最后单次消费答复
- 一次性卡号：OneTimeCard 绑定商家/金额/货币/有效期，单次
兑现；SimulatedWalletBackend 沙箱钱包（假 PAN 只在后端
私有内存、charge 只记账不联网、取消即 void）
- 限额：SpendLimits 三档 minor units 比对，限额不可用时
不编造上限（limits_checked=False）
- 审计：PaymentAudit 只留允许字段，秘密字段名丢弃 + redacted
- 审批通道最小扩展：ApprovalRequest 增加可选 details 字段，
不传时 payload 与 P5 完全一致
- 真实支付与扣款不做：全部沙箱验证，真实钱包集成待用户
另行批准；新测试 79 项，全量 cloud 套件 2037 OK
round-12 集成说明：本提交为 acf98f8 的 cherry-pick（只含 P10
自有 diff，基线 25bcd35 已含的 P3/P5 内容未重复合入；
approval_channel.py 仅加可选 details 字段）。

"""对齐 Muse P10 支付安全门端到端测试：PaymentGate 编排。
|
||||
|
||||
只用标准库、假时钟与沙箱钱包，绝不启动真实 VM、不联网、
|
||||
不产生真实扣款。覆盖：
|
||||
- 完整购买链（检测 → 路由 → 限额 → 审批 → 铸卡 → 记账）；
|
||||
- 审批 payload 含确切购买详情；无 details 时 payload 与 P5 一致；
|
||||
- 无审批不支付、对话内伪造批准无效、答复过期/重放无效；
|
||||
- 详情被篡改即拒且审批保持待处理（同一答复换正确详情仍可用）；
|
||||
- 审批拒绝即停、不扣款；超限额审批前即拒；限额不可用时不编造；
|
||||
- 无钱包路由即拒；已保存凭证路由；取消待支付；扣款失败 void 卡；
|
||||
- 审计里绝无卡号。
