fix: 修改相关概念组件以匹配真实API数据结构

修改内容：
- SimpleConceptCard.js: 改用 concept.concept 和 concept.score 字段
- DetailedConceptCard.js: 改用 concept.concept、concept.score 和 concept.price_info.avg_change_pct
- RelatedConceptsSection/index.js: 导航时使用 concept.concept 字段
- events.js mock数据: 更新keywords生成函数，使用concept/score/price_info结构

数据结构变更：
- name → concept (概念名称)
- relevance (0-100) → score (0-1)
- avg_change_pct → price_info.avg_change_pct (嵌套结构)
