fix(frontend): 卡密兑换通知接入全局 notyf Toast 固定 id 流

- credits.js initCardPass 从 setTip 内联提示迁移为固定 id 三态 notyf 流
  （aksrt-card-pass-toast：load → success/danger 原位更新），
  成功后延迟 800ms 刷新以保证成功 Toast 可见，对齐其余资产操作。
- credits-wallet.php 删除 data-aksrt-card-tip 死元素；credits.css 删除
  .uc-card-pass__tip 死样式。
- 契约：toast-contract 将卡密兑换纳入固定 id 流清单并禁止 tip 回潮；
  card-pass-universal-redeem 新增 Toast 流断言（27/27 通过）。
- 验证：容器内真实抓取 /user/balance/ 确认弹窗正常渲染且无 tip 残留。
