docs(job-queue-dependencies): add documentation for job queue setup and configuration

- Created a new document detailing the dependencies required for the job queue implementation using Bull and IORedis.
- Included installation instructions, Redis setup, environment variable configuration, and usage examples for the RecurringTasksService.
- Highlighted the benefits of using job queues over cron jobs and provided monitoring options for job queues.

+# Job Queue Dependencies
+
+To use the job queue implementation for recurring tasks, add these dependencies to your package.json:
+
+```json
+{
+  "dependencies": {
+    "bull": "^4.12.2",
+    "ioredis": "^5.3.2"
+  },
+  "devDependencies": {
+    "@types/bull": "^4.10.0"
+  }
+}
+```
+
+## Installation
+
+```bash
+npm install bull ioredis
+npm install --save-dev @types/bull
+```
+
+## Redis Setup
+
+1. Install Redis on your system:
+   - **Ubuntu/Debian**: `sudo apt install redis-server`
+   - **macOS**: `brew install redis`
+   - **Windows**: Use WSL or Redis for Windows
+   - **Docker**: `docker run -d -p 6379:6379 redis:alpine`
+
+2. Configure Redis connection in your environment variables:
+   ```env
+   REDIS_HOST=localhost
+   REDIS_PORT=6379
+   REDIS_PASSWORD=your_password  # Optional
+   REDIS_DB=0
+   ```
+
+## Configuration
+
+Add these environment variables to control the recurring tasks behavior:
+
+```env
+# Service configuration
+RECURRING_TASKS_ENABLED=true
+RECURRING_TASKS_MODE=queue  # or 'cron'
+
+# Queue configuration
+RECURRING_TASKS_MAX_CONCURRENCY=5
+RECURRING_TASKS_RETRY_ATTEMPTS=3
+RECURRING_TASKS_RETRY_DELAY=2000
+
+# Notifications
+RECURRING_TASKS_NOTIFICATIONS_ENABLED=true
+RECURRING_TASKS_EMAIL_NOTIFICATIONS=true
+RECURRING_TASKS_PUSH_NOTIFICATIONS=true
+RECURRING_TASKS_IN_APP_NOTIFICATIONS=true
+
+# Audit logging
+RECURRING_TASKS_AUDIT_LOG_ENABLED=true
+RECURRING_TASKS_AUDIT_RETENTION_DAYS=90
+```
+
+## Usage
+
+In your main application file, start the service:
+
+```typescript
+import { RecurringTasksService } from './src/services/recurring-tasks-service';
+
+// Start the service
+await RecurringTasksService.start();
+
+// Get status
+const status = await RecurringTasksService.getStatus();
+console.log('Recurring tasks status:', status);
+
+// Health check
+const health = await RecurringTasksService.healthCheck();
+console.log('Health check:', health);
+```
+
+## Benefits of Job Queue vs Cron
+
+### Job Queue (Bull/BullMQ) Benefits:
+- **Better scalability**: Can run multiple workers
+- **Retry logic**: Built-in retry with exponential backoff
+- **Monitoring**: Redis-based job monitoring and UI
+- **Priority queues**: Handle urgent tasks first
+- **Rate limiting**: Control processing rate
+- **Persistence**: Jobs survive server restarts
+
+### Cron Job Benefits:
+- **Simplicity**: No external dependencies
+- **Lower resource usage**: No Redis required
+- **Predictable timing**: Runs exactly on schedule
+- **Easier debugging**: Simpler execution model
+
+## Monitoring
+
+You can monitor the job queues using:
+- **Bull Dashboard**: Web UI for monitoring jobs
+- **Redis CLI**: Direct Redis monitoring
+- **Application logs**: Built-in audit logging
+- **Health checks**: Built-in health check endpoint
+
+Install Bull Dashboard for monitoring:
+```bash
+npm install -g bull-board
+```

+
+/*
+USAGE:
+
+1. First, run the detection queries to see which projects have duplicates
+2. Then run this to fix all duplicates:
+   SELECT fix_all_duplicate_sort_orders();
+3. Finally, verify the fix worked:
+   SELECT * FROM verify_sort_order_integrity();
+   
+If verification returns no rows, all duplicates have been fixed successfully.
+
+WARNING: This will reassign sort order values based on current order + creation time.
+Make sure to backup your database before running these functions.
