- 编辑器投稿页布局优化：标题与编辑器高度动态适配，工具栏与内容区视觉对齐 - 稿件展示页布局优化：MD 渲染区与评论区视觉分离，代码块主题微调 - CSRF 中间件：图像上传端点豁免，解决 Vditor 拖拽/粘贴上传 403 - Post 状态映射、GetGinUser、SaveUploadedFile 提取至 common 包，遵循审计建议 - 新增个人空间功能：/space（需登录）重定向到 /space/:uid，/space/:uid 公开访问 - 空间页模板：参考 B 站布局，展示头像、用户名、个性签名、UID、加入时间及稿件列表 - 导航栏：用户名链接指向 /space，新增「设置」入口 - 分层实现：SpaceController → SpaceService → PostRepo.FindByUserID，严格 ISP 接口隔离
