feat(health-main): 意图问卷入口 + 跳过提醒机制

后端:
- UserIntent实体新增skipCount/lastSkipAt字段
- 新增POST /api/user-intent/skip 接口记录跳过次数
- 迁移243: user_intents表添加skip_count和last_skip_at列

前端:
- 新增pages/health/intent-quiz.vue意图问卷入口页（三选一：随便看看/先了解自己/解决问题+以后再说）
- health-main新增showIntentReminder状态，跳过1-2次后显示提醒横幅
- 跳转逻辑：A类→返回浏览 / B类→AI问卷 / C类→问题域选择

设计说明:
- 所有用户从统一入口开始（intent-quiz页面）
- 随便看看用户点击以后再说，记录skipCount，最多提醒3次
- 先了解自己/解决问题用户直接进入AI智能问卷或问题域选择
