feat(phase-6): Bulk CSV processing and background worker implementation

- Add BulkJob model to Prisma schema with relations
- Implement BulkProcessorService for CSV parsing and job management
- Create BulkTrackingWorker for background processing with BullMQ
- Add comprehensive bulk API routes (upload, jobs, progress, export)
- Integrate multer for CSV file uploads with validation
- Add job progress tracking and estimation
- Implement CSV export functionality for results
- Add queue statistics and cleanup endpoints
- Create shared types for bulk processing
- Add comprehensive test suite for all bulk functionality
- Implement graceful worker shutdown and error handling
- Add rate limiting and authentication for all bulk endpoints

Backward compatibility: Maintained for /api/track and /api/v1/track
