fix: 测试反馈0403修改 — 百科Bug修复/份数→克数/AI对话增强/流式输出

1. [P0] food-encyclopedia: 修复 goToFoodDetail TypeError 报错
   - 增加 item 空值防御性校验
   - 加固 filteredFoodList 过滤无效项

2. [P1] calculator-result: 食物份数建议改为克数
   - 模板展示从"X份"改为"X克"
   - applyResult 数据适配：优先读 gram 字段，兜底 portion * gramPerServing 换算

3. [P2] ai-nutritionist: 新增消息操作按钮（复制/重新生成/删除）
   - AI消息气泡下方新增 msg-actions 按钮组
   - 复制到剪贴板、删除单条消息、重新生成最后一条AI回复

4. [P2] ai-nutritionist + models-api: 启用流式输出改善响应速度
   - 新增 kieaiGeminiChatStream 函数（SSE + enableChunked）
   - sendToAI 优先走流式，失败自动降级为非流式
