feat(chat): DTK 主窗口 + 新模型；fix(panel): 菜单位置/工厂挤压与误隐藏

- ChatWindow 改为 DMainWindow + DTitlebar，图标按 DPR 取图
- DeepSeek 模型改为 deepseek-flash / deepseek-v4-pro，设置里可拉取 /models
- 内容工厂右侧常驻「问问小埃同学」大按钮，移除传送门上的常驻入口
- 工厂出现时面板整体上移预留空间，不再挤压传送门
- 工厂隐藏改为检查指针是否仍在面板内，拖进工厂不再消失
- 右键菜单超出屏幕时向上弹出
- 移除 512 图标（由 293px 源图放大，发糊）
