后端：
- ToolKnowledgeService/Impl 新增 generateNutrientContent()
调用 Coze AI 批量生成6种营养素（蛋白质/钾/磷/钠/钙/水分）
科普内容并写入 v2_knowledge，已存在的自动跳过
- ToolController 新增 POST /tool/knowledge/generate-nutrients
端点（管理端一次性调用后自动补充封面图）
- 新增 SQL 备用脚本 migration_2026-03-25_nutrient_knowledge.sql
含6种营养素完整JSON，直接执行可跳过AI生成
前端（ai-nutritionist.vue，对齐功能开发详细设计文档任务3-2）：
- 新增 sleep(ms) 工具方法
- sendToAI 发起前先推入 {loading:true} 占位气泡
- pollChatStatus 轮询间隔由 1000ms 调整为 1500ms
- getChatMessages 回调填充占位气泡（不再 push 新消息）
- 所有错误/超时/失败路径统一更新 aiMsg.loading=false
