feat(admin): 计费页长出「充值渠道」块 —— 兑换码生成/台账 + 积分包定价

P5.1 收尾:此前生成码只有 API。计费页现在从上到下 = 计费规则(积分→token
汇率) → 充值渠道(钱→积分:兑换码 + 微信定价用的积分包) → 用量观测,
两层汇率在同一页可见、各管各的。

- 兑换码:面额/张数/备注生成;**明文码只在生成响应显示一次**(等同现金,
  台账 GET /admin/redeem-codes 服务端脱敏只露首尾,丢码重生成、不提供找回
  ——顺手把接口这个第二明文出口堵了);台账含核销状态。
- 积分包:新增/上下架(微信 P5.2 上线前把定价面备好);admin api.ts 补
  packs/redeem-codes 四个函数。
- launch.json 加 admin-console-alt(:5176)——5174 被用户自己的 sundynix-site
  占着,不动别人端口。
live:5176 登录→生成 5 张(绿色一次性面板+复制全部)→配「入门包 1000分/¥9.9」
在售可下架→台账脱敏 curl 复核;tsc+41 vitest 全绿。
