Root cause: ngx-echarts v18+ requires provideEcharts() in the app
config. Without it, NgxEchartsDirective silently fails to render
charts, causing the dashboard overview chart to appear empty.
Added provideEcharts() to app.config.ts and added
DashboardServiceIntegrationTest for the metering data overview endpoint.
