Bernhard Müller 0ef4f94933 fix(frontend): add error handling for dashboard overview metering data API ... The empty error callback in loadMeteringData() silently swallowed API failures, causing the chart to show 'Keine Daten' instead of the actual error. Added proper error logging and user-facing error message. Also added DashboardServiceTest for getMeteringDataOverview with scenarios for data, no metering points, empty time range, and multiple metering points.		2026-07-24 15:27:36 +02:00
