New feature: combined historical + forecast burndown chart with metric
selector on the CCP Metrics page. Shows stacked bars (total assets vs
non-compliant) with a compliance percentage trend line. A bold divider
separates actual historical data from projected future remediation.
Forecast assumes constant asset count and on-schedule remediation plans.
Backend:
- computeMetricForecastBurndown helper in vclHelpers.js (pure function)
- GET /api/compliance/vcl-multi/metrics-list endpoint
- GET /api/compliance/vcl-multi/metric/:metricId/forecast-burndown endpoint
Frontend:
- MetricSelector dropdown with device counts per metric
- ForecastBurndownChart using recharts ComposedChart (Bar + Line + ReferenceLine)
- Forecast bars render at 50% opacity to distinguish from actuals
- Race condition handling for rapid metric switching
- Queue panel width increased from 420px to 600px
