feat: add 24-hour traffic and capacity trend charts to dashboard and node detail pages

- Implemented TrendChart component for visualizing traffic and capacity trends. - Enhanced DashboardOverview and NodeDetailPage components to display 24-hour request and capacity trends. - Updated types to include traffic and capacity trend data structures. - Created observability trends service to aggregate traffic and capacity data. - Added tests for traffic report generation and trend data handling. - Introduced new dependencies for charting (echarts and echarts-for-react).
