feat(user): 全面优化用户管理页面交互和显示效果

主要优化：
- 修复角色分配回显问题，编辑时正确加载用户完整信息
- 优化邮箱字段tooltip显示，解决文字颜色不清晰问题
- 美化角色分配标签，采用主题色渐变设计
- 统一操作按钮样式，使用圆形按钮和悬浮效果
- 新增NovaEmpty空状态组件，提升无数据时用户体验

技术改进：
- 编辑用户时调用getUserById获取完整roleIds信息
- 自定义renderRoleTag函数，优化角色标签视觉效果
- 修复tooltip文字继承灰色样式导致不清晰的问题
- 移除用户类型标签圆角，保持界面设计一致性
- 操作列宽度优化，按钮间距和布局更加紧凑

交互体验：
- 角色标签支持悬停动效和渐变背景
- 操作按钮tooltip提示更加友好
- 空状态页面提供智能操作建议
