[CONST-D-002] feat: Add dashboard API endpoints to reports controller

- GET /reports/dashboard/stats - Dashboard aggregate statistics
- GET /reports/projects/summary - Projects summary with EVM KPIs
- GET /reports/projects/:id/kpis - Project KPIs
- GET /reports/projects/:id/earned-value - EVM metrics
- GET /reports/projects/:id/s-curve - S-curve data
- GET /reports/alerts - Active alerts
- PATCH /reports/alerts/:id/acknowledge|resolve

Integrates EarnedValueService for EVM calculations.
