fix: token 过期时前端自动清除登录态并跳转登录

根因: 页面使用 uni.request() 直接请求，401 时只有静默 catch，
不清除本地 token，导致界面显示已登录但后端拒接。

修复:
- 新增 utils/auth.ts: clearAuth() + checkAuth() 统一处理 401
- member.vue: refreshState / startGravityPay / startPlanPay /
  pollPayResult / activatePlan 全部添加 401 检测
- user.vue: fetchUserInfo / loadMemberStatus / loadStats /
  preCreateShare 添加 401 检测
- interview.vue: startInterview / sendAnswer / speakAiText /
  startRecord 添加 401 检测
