Backend changes:
- Add sync_jobs table for background job tracking with Drizzle schema
- Create job queue service (job-queue.service.js) for async job processing
- Only ONE active sync job per user enforced at queue level
- Refactor LoTW service with Wavelog download logic:
- Validate for "Username/password incorrect" in response
- Check file starts with "ARRL Logbook of the World Status Report"
- Use last LoTW QSL date for incremental sync (qso_qslsince)
- Wavelog-compatible timeouts and error handling
- Add deleteQSOs function to clear all user QSOs
- Fix database path to use absolute path for consistency
- Register job processor for lotw_sync job type
API endpoints:
- POST /api/lotw/sync - Queue background sync job, returns jobId immediately
- GET /api/jobs/:jobId - Get job status with progress tracking
- GET /api/jobs/active - Get user's active job
- GET /api/jobs - Get user's recent jobs
- DELETE /api/qsos/all - Delete all QSOs for authenticated user
Frontend changes:
- Add job polling every 2 seconds during sync
- Show real-time progress indicator during sync
- Add "Clear All QSOs" button with type-to-confirm ("DELETE")
- Check for active job on mount to resume polling after refresh
- Clean up polling interval on component unmount
- Update API client with jobsAPI methods (getStatus, getActive, getRecent)
Database:
- Add sync_jobs table: id, userId, status, type, startedAt, completedAt,
result, error, createdAt
- Foreign key to users table
- Path fix: now uses src/backend/award.db consistently
