## 2. Backend - Firebase Client

### firebase.client.ts (~300 lineas)
```typescript
class FirebaseClient {
  private app: admin.app.App | null = null;

  initialize(): void  // Init con service account

  async sendToDevice(token: string, payload: NotificationPayload): Promise<boolean>

  async sendToMultiple(tokens: string[], payload: NotificationPayload): Promise<SendResult>

  async deactivateInvalidTokens(tokens: string[]): Promise<void>
}

export const firebaseClient = new FirebaseClient();
```

### config/index.ts (modificado)
```typescript
firebase: {
  serviceAccountKey: process.env.FIREBASE_SERVICE_ACCOUNT_KEY || '',
  projectId: process.env.FIREBASE_PROJECT_ID || '',
},
webPush: {
  publicKey: process.env.VAPID_PUBLIC_KEY || '',
  privateKey: process.env.VAPID_PRIVATE_KEY || '',
  subject: process.env.VAPID_SUBJECT || 'mailto:admin@orbiquant.io',
},
```

### notification.controller.ts (modificado)
```typescript
// Nuevos endpoints
export async function registerPushToken(req: AuthenticatedRequest, res: Response)
export async function removePushToken(req: AuthenticatedRequest, res: Response)
```

### notification.routes.ts (modificado)
```typescript
router.post('/push-token', authHandler(registerPushToken));
router.delete('/push-token', authHandler(removePushToken));
```

## 3. Tests Unitarios

### notification.service.spec.ts (~450 lineas)
- Mocks: db, wsManager, nodemailer, firebaseClient
- Tests: sendNotification, getUserNotifications, markAsRead, etc.

### distribution.job.spec.ts (~380 lineas)

```typescript
interface NotificationState {
  notifications: Notification[];
  unreadCount: number;
  preferences: NotificationPreferences | null;
  loading: boolean;
  error: string | null;

  fetchNotifications: (unreadOnly?: boolean) => Promise<void>;
  fetchUnreadCount: () => Promise<void>;
  markAsRead: (id: string) => Promise<void>;
  markAllAsRead: () => Promise<void>;
  addNotification: (notification: Notification) => void;
  initializeWebSocket: () => () => void;
}
```
