/**
 * 审核未通过页 U17 / H11（Phase 05 P05-T17）
 *
 * 重构要点（遵循 AGENTS.md 不变量）：
 *   - 数据：userStore.fetchReviewStatus（取 items[] 逐项驳回原因）
 *   - 展示：每项明确 itemType → 中文标签 + reasonText + "立即修改"跳转对应资料页
 *   - 路由守卫：onShow 检查 userState，若状态变为 approved → reLaunch 首页；
 *     若变为 pending → redirectTo 审核中页
 *   - AGENTS 第 9 条：DB 是 Source of Truth——审核结果以服务端 items 为准，
 *     本地不缓存驳回原因；每次进入页面重新拉取
 *   - AGENTS 第 2 条：Required 不可自动放宽——本页仅引导修改，不修改任何择偶条件
