feat: 记录详情页Canvas按轮次分组展示，对话面板UI重构与视觉升级

- Canvas视图重构：记录详情页用 turn-groups 按生成轮次分组替代原 canvas-nodes，支持生成中/失败状态展示及拖拽定位
- 对话面板头部改为 title + actions 布局，新增首页返回按钮，移除独立 toggle
- 对话收起时显示 recall 入口卡片，展示当前轮次摘要信息并支持一键展开继续对话
- 历史记录侧边栏列表项新增状态 class（is-generating/is-failed/is-done），元信息拆分为类型+状态标签结构
- CSS 新增 1772 行：记录详情页整体视觉升级（渐变背景、毛玻璃面板、胶囊卡片、状态色条），Canvas 节点响应式布局，Preview modal 底部操作栏美化
