fix: cannot paste images when mentioned visual models (#7817)

* refactor(paste): 优化粘贴功能逻辑，移除模型类型依赖

重构粘贴服务处理逻辑，将文件类型支持判断移至组件层
简化handlePaste接口，移除isVisionModel和isGenerateImageModel参数

* fix(MessageEditor): 支持生成图片模型的视觉消息检查

* refactor(Inputbar): 移除调试用的console.log语句

* refactor(PasteService): 移除调试用的console.log语句
