fix(auth): 修复活动页和商品详情页未登录即弹登录框导致审核失败

问题背景：
- 平台审核结论：页面未完整浏览、体验详情时即要求授权登录，属于不合规
- 用户应能先浏览页面内容，仅在执行操作（抽奖/兑换/购买）时才引导登录

根因分析：
1. api/appUser.js 中活动浏览类 API（getActivityDetail 等）使用 authRequest，
   虽然后端接口是公开的，但同页面的 getGamePasses 等需认证接口返回 401
   触发全局登录弹窗
2. getProductDetail 使用 authRequest 调用认证接口，未登录直接 401
3. 全局 401 拦截器不区分浏览请求和操作请求

修改内容：
1. api/appUser.js: 6 个浏览类 API 函数从 authRequest 改为 request
   - getActivityDetail, getActivityIssues, getActivityIssueRewards
   - getIssueDrawLogs, getMatchingCardTypes, getProductDetail
   这些接口在后端均为公开路由，不需要携带 token

2. 活动页面 onLoad 中条件调用认证接口：
   - wuxianshang/index.vue: fetchPasses() 仅在已登录时调用
   - yifanshang/index.vue: fetchPasses() 仅在已登录时调用
   - duiduipeng/index.vue: fetchGamePasses() 仅在已登录时调用
   次数卡（game passes）接口需要认证，未登录时跳过即可，
   不影响页面浏览体验

3. utils/request.js: request() 函数增加 suppressAuthModal 参数
   支持调用方按需静默 401 弹窗，作为安全兜底机制

验证场景：
- 未登录 → 打开无限赏/一番赏/对对碰/商品详情 → 正常显示，无登录弹窗
- 未登录 → 点击抽奖/兑换按钮 → 弹出登录提示（符合平台规范）
- 已登录 → 所有功能正常，次数卡信息正常加载
