# Change: Add Project Health Dashboard

## Why
MED-006: The `Multi-Project Health Dashboard` requirement exists in the spec but has no implementation. Managers cannot view an overview of all projects' health status, making it difficult to identify at-risk projects.

## What Changes
- Add `pjctrl_project_health` database table and migration
- Implement backend API endpoints for project health data
- Create frontend Project Health Dashboard page
- Add health score calculation service

## Impact
- Affected specs: resource-management
- Affected code:
  - `backend/app/models/project_health.py` (new)
  - `backend/app/api/health/router.py` (new)
  - `backend/app/services/health_service.py` (new)
  - `frontend/src/pages/ProjectHealthPage.tsx` (new)
