fix(miniprogram): 修复多角色找茬测试 V3 发现的 8 个问题

1. EmptyState 默认 emoji 📭 → serif 首字圆形图标（影响 23 处使用）
2. 预约页英文副标题 "Appointment" 移除
3. consultation 页技术错误信息直接渲染到 UI → 用户友好提示
4. auth store restore() 增加 fallback：secureGet 失败时读 wx.getStorageSync
5. request.ts 新增 safeGet()：token/tenantId 读取容错
6. doctor/consultation useMemo 自引用死循环 → Math.ceil(total/20)
7. doctor/alerts 同样自引用 bug 修复
8. doctor/patients 死代码 totalPages + useMemo import 清理
