fix(pay): 支付方式字样与按钮 UI 三弹窗统一对齐 Zibll

渠道展示名与按钮 UI 与参考主题 zibpay_get_payment_method_args /
zibpay_get_initiate_pay_input 对齐：

- 渠道名：aksrt_list_cash_payment_methods 增加 Zibll 基准展示名映射
  （余额/支付宝/微信/PayPal/Stripe），充值与会员弹窗不再显示网关
  内部名「站内余额」「微信支付」；积分弹窗手写「余额/卡密」与之同源
- 会员按钮字样：cta_label（立即开通/立即续费）→ Zibll 会员弹窗
  initiate_pay_input(4) 默认「立即支付」，与充值/积分弹窗一致
- 无可用支付方式：禁用按钮+自实现文案 → Zibll 同款
  <span class="badg px12 c-yellow-2">暂时无法支付，请与客服联系</span>
- 清理：按钮残留类 aksrt-vip-submit 与对应 CSS，加载/禁用态统一挂
  .initiate-pay（三弹窗按钮共用）；renderMethods 空数组重复提示与
  不可达 reason 映射删除
- 契约测试同步锁定（无 cta_label/aksrt-vip-submit、立即支付字样、
  badg 提示、渠道名映射）

弹窗宽度差异（充值/积分 400px modal-mini、会员 600px）为 Zibll
原生设计，已在壳几何对齐时确认一致。
