refactor: space页面改为卡片式关注列表布局

- 重写 space/index.html：左右分栏，左侧导航栏 + 右侧卡片网格
- 自己空间：显示全部关注用户卡片（头像/用户名/简介/已关注标签）+ 设置入口
- 他人空间：简化侧栏（Ta的关注/粉丝），隐私关闭时显示空状态插图
- Model UserFollow 新增头像/简介联表字段
- Repository ListFollowing/ListFollowers SELECT 增加 avatar/bio
- Controller ShowSpace 注入 FollowService，获取关注列表数据
- space.css 完全重写为卡片网格布局 + 响应式适配
- follow.css 清理旧 .follow-btn/.follow-links 无用样式
