feat(report): 重构统计报告页面，引入全新现代化UI主题

本次提交对统计报告页面进行了一次全面的视觉和代码重构，旨在提升用户体验和可维护性。

主要更新包括：
- **UI/UX 重构**: 废弃原有的 Material Design 3 主题，采用更简洁、现代的仪表盘风格，优化了色彩、字体和布局，提升了整体视觉效果和数据可读性。
- **布局优化**: 使用 CSS Grid 构建主布局，提高了响应式设计的灵活性和健壮性。
- **图表美化**: 更新了所有图表的视觉样式，包括新的调色板、交互式工具提示和更清晰的坐标轴。
- **代码优化**:
  - 将图表数据从内联 JavaScript 字符串改为通过 `<script type="application/json">` 标签注入，更加安全和规范。
  - 实现了图表的懒加载，仅在切换到对应标签页时才进行初始化，提升了初始加载速度。
  - 移除大量内联样式，统一使用 CSS 类进行管理，增强了代码的可维护性。
