feat(self-check): 通过 AiGateway 接入智能出题能力，新增 POST /api/family/self-check/ai-generate-questions

- 移除裸 RestTemplate 服务 LangGraphService.java（未跟踪 WIP，3 处缺陷 + 架构冲突）
- AiGateway 新增 generateSelfCheckQuestions(Map) 方法，调 /api/v1/question-generate
- FiveDimensionSelfCheckController 新增 ai-generate-questions 路由，返回 Result<List<SelfCheckQuestionVO>>
- questions 列表的 options 字段暂不映射，待后续补全

解除了本地 mvn clean compile 因 LangGraphService 导致的构建中断
