refactor: 优化导航栏布局和命名

UI优化:
- 简化导航栏菜单名称，提升用户体验
  * 项目管理  项目
  * 模特管理  模特
  * 模板管理  模板
  * 素材绑定  素材
  * AI分类设置  分类
  * 服装搭配  穿搭
  * 便捷工具  工具

布局调整:
- 优化导航栏间距和内边距，更加紧凑
- 调整主容器滚动区域到main元素
- 减少导航项之间的间距(space-x-4  space-x-2)
- 优化内边距(px-3  px-2, ml-10  ml-4)

代码清理:
- 移除未使用的CogIcon导入
- 移除应用设置相关的导航项

这些调整让导航栏更加简洁明了，提升了界面的整体美观度
