fix: 修复手动测试发现的3项问题

1. food-encyclopedia: 修复 v-for key id:index TypeError
   - :key 改为 :key="index"，避免 WeChat 小程序 key 表达式异常
   - filteredFoodList 加本地搜索过滤 + null item 过滤
   - normalizeFoodItem 新增英文→中文分类名映射（grain→谷薯类等）
   - loadFoodList/handleSearch 过滤 null 条目

2. ToolKnowledgeServiceImpl: 修复 TooManyResultsException
   - getNutrientDetail 查询新增 LIMIT 1 + ORDER BY knowledge_id DESC
   - 防止 DB 中同名营养素存在多条导致 selectOne 异常

3. ai-nutritionist: 统一走 Coze API，移除 KieAI Gemini 路径
   - sendToAI 文本/多模态均改为 api.cozeChat + pollChatStatus
   - 支持 type='text'/'multimodal'/图片 三种消息类型构建
