feat(health): 健康问卷按性别/年龄动态调整问题

- LifestyleStep 新增 profile prop，按 gender/age 动态渲染：
  · 女性专属：月经周期规律性 + 特殊时期（备孕/怀孕/哺乳）
  · 儿童（<12）：生长发育 + 挑食情况
  · 青少年（12-18）：屏幕时间 + 情绪状态
  · 老年（≥60）：骨质疏松风险 + 跌倒风险
- MemberChipPicker 透传 gender/age
- health-plan-summary 新增 memberProfileMap 计算属性 + 传递给向导
- HealthQuestionnaireWizard 新增 memberProfileMap prop + currentMemberProfile 计算
- buildHealthPayload/parseLifestyle 包含全部 lifestyle 新字段
- LangGraph adapter 消费 lifestyle + diet_structure，prompt 不确定时提示菌群检测
- health_plan.py 新增 MultiMemberPlanResponse（多成员方案）
- 修复 mergeWizardForm 丢失 lifestyle 字段 bug

+1. **common**：出现在至少两个成员方案中的相似/重复内容。包括：共同适用的饮食大方向、共同的生活习惯、所有人都需要执行的锻炼/打卡等。**common 的 sections 应保留完整 tasks，因为这些任务会分配给每个成员各一份。**
+2. **individual.<memberId>**：只适用于该成员独有的内容，包括：针对该成员专属指标异常的建议、该成员特有的疾病史/过敏史、年龄相关的个性化建议等。该成员的个性 section 不能包含已放入 common 的内容（避免重复）。
+3. 如果某成员没有独有内容，其 individual 的 sections 为空数组 `[]`，overview 写"无"，abnormal_indicators 为 `[]`。
+4. **abnormal_indicators**：多成员共有的异常指标放入 common；只属于某个成员的异常指标放入 individual 该成员的 abnormal_indicators。
+5. knowledge_sources 不输出。
+
+## 任务约定
+- `action_type` 取值仅限：`buy`（购买/补充产品）、`read`（阅读）、`exercise`（运动）、`checkin`（打卡/记录）、`diet`（饮食）、`activity`（活动/社交）。
+- `dimension` 取值仅限五维：`body`/`mind`/`wisdom`/`action`/`wealth`。
+- `frequency`：`once`=一次性任务；`daily`=每日重复任务。
+- `title` 必须是**具体可执行的动作**，不要写纯原理/机制描述。
+- 若某 section 没有可执行的行动项，`tasks` 输出空数组 `[]`。"""
