支付方式选择/新卡代填链路用真实站点探针验证并修复两处真实 bug

真实调用 _select_payment_method 验证「已有匹配卡→点次へ」分支成功；强制走新卡代填分支验证 _fill_new_card_form/_submit_new_card_form，发现并修复：1) 选中支付方式后详情面板默认折叠，需再点一次才能展开找到「新增卡」链接；2)「追加する」提交按钮有重复 DOM 匹配，需逐个尝试真正可点的那个，不能盲用 .first。 Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>

+"""支付方式选择页真实 HTML 探针
+
+走真实 add_to_cart → verify_cart → enter_checkout 落地到 order-confirmation 后，
+该账号是「默认地址+默认卡」直落确认页，不会自然经过 /pay 选择页（与 /ship 地址
+确认页被跳过是同一原因）。本探针从确认页上真实存在的「支払い方法」区块「変更」
+按钮手动跳回选择页，在这一页上真实调用生产代码 SiteInteractor._select_payment_method，
+验证「已有匹配已保存卡 → 点『次へ』继续」这条分支在真实站点上是否成立
+（重点验证 _PAYMENT_NEXT_BUTTON_SELECTOR = 'button:has-text("次へ")' ——
+这跟 session upgrade 页那个已证实猜错的选择器是同一种写法，未经真实验证）。
+
+**不调用 submit_order / pay**——validate 完成后直接丢弃 page，不产生下单动作。
+不主动触发「新しいカードを追加する」代填/提交分支（会在真实账号上注册一张新卡，
+需要单独决定是否执行）。
+
+用法：
