Docker deployment working - core system operational

Successfully deployed ShopDB in Docker with pre-built frontend approach.

WORKING:
- MySQL 8.4 database (healthy)
- Flask API with HTTPS on port 5001
- Gunicorn with 4 gevent workers
- All 17 plugins installed, 12 enabled
- Frontend built and served via Vue 3 SPA
- Auto-bootstrap on first deployment

BUILD APPROACH:
- Build frontend on host (bypasses Zscaler npm issues)
- Copy pre-built dist/ into Docker image
- Simple Python-only Dockerfile (no npm in container)
- Build time: 2-3 minutes (vs 15+ for failed multi-stage)

NOT WORKING YET:
- Backup watcher service (Oracle Linux SSL cert issues with Zscaler)
- Manual backups still functional via one-shot container

VERIFICATION:
- curl -k https://localhost:5001/ returns HTML
- curl -k https://localhost:5001/api/settings returns JSON
- 4 gunicorn workers running
- Database migrations applied

Files:
- DOCKER-DEPLOYMENT-COMPLETE.md: Full deployment guide
- scripts/backup/zscaler-root-ca.pem: Zscaler cert for backup containers
- .dockerignore: Updated to allow frontend/dist

For production: Set up CI/CD to build images and push to registry.
