feat(agent): 支持自建风格与智能体双模式对话系统

- 新增 `source` 字段区分智能体(`agent`)与自建风格(`prompt`)两种对话来源 - 前端统一对话组件，根据来源动态构建请求参数、显示不同样式与文案 - 后端重构 Dify 会话与消息获取逻辑，支持合并查询 Pro 与 Standard 两个 Dify App 的会话历史 - 实现复合游标分页机制，支持跨双数据源的高效分页 - 新增 `clipboard-polyfill` 依赖，统一剪贴板复制功能，提升非 HTTPS 环境兼容性 - 扩展历史记录面板，支持按来源加载对应会话与消息 - 调整侧边抽屉宽度，优化大屏显示体验
