## 📋 RESUMEN EJECUTIVO

### Problema Original
Portal Admin mostraba errores críticos al cargar el dashboard:
- `Cannot read properties of undefined (reading 'health')` en adminAPI.ts:825
- `Cannot read properties of undefined (reading 'metrics')` en adminAPI.ts:841
- `Cannot read properties of undefined (reading 'map')` en adminAPI.ts:115, 138

### Causa Raíz
El archivo `/config/api.config.ts` tenía estructura incompleta:
- ❌ Namespace `admin` carecía de sub-namespaces anidados (`system`, `organizations`, `users`, etc.)
- ❌ Namespace `teacher` carecía de sub-namespace `dashboard` anidado
- ❌ Namespace `educational` carecía de múltiples endpoints usados por el código

### Solución Implementada
Completar el archivo `/config/api.config.ts` con **80+ endpoints faltantes** distribuidos en 3 namespaces principales.

## 📝 NOTAS TÉCNICAS

### Patrón de Estructura Anidada
Se usó estructura anidada para permitir agrupación lógica:
```typescript
admin: {
  system: {
    health: '/admin/system/health',
    metrics: '/admin/system/metrics',
  }
}
```

Esto permite acceso como: `API_ENDPOINTS.admin.system.health`

### Compatibilidad con Código Existente
Se mantuvieron endpoints planos donde el código ya los usaba:
```typescript
// Nested (nuevo código)
API_ENDPOINTS.admin.organizations.list

// Flat (código legacy)
API_ENDPOINTS.admin.organization(id)
```

Ambos coexisten para evitar breaking changes.

### Alineación con Backend
Todos los endpoints agregados están alineados con las rutas definidas en:
`apps/backend/src/shared/constants/routes.constants.ts`
