权限监控与管理界面全面美化

重新设计权限系统所有 UI 组件的视觉风格，统一配色、圆角、阴影和交互动效：
- 实时概览：统计卡片加图标和渐变色条，健康评分改为环形进度，告警改为卡片式
- 趋势分析：图表卡片加彩色图标标识，ECharts 配色升级为渐变面积填充
- 访问日志：指标卡片带图标，日志审计改为卡片式入口，IP排行前三高亮
- IP属地：工具栏重设计，排行列表前三渐变高亮，指标卡片统一新风格
- 系统级权限：从 el-table 改为自定义卡片列表，模块块独立圆角卡片
- 项目权限配置：空状态引导优化，成员表格加头像，工具栏加背景容器
- 角色概览卡片：加进度条可视化，hover 微动效
- 接口权限矩阵：工具栏分离布局，表格圆角包裹
- 角色管理抽屉：侧边栏选中态渐变，操作行 hover 高亮
