Prepare repository for public deployment

- Replace ReportLab PDF export with LibreOffice headless for proper DOCX formatting preservation
- Add libreoffice-writer + fonts-liberation to backend Dockerfile
- Proxy public CV PDFs through frontend (/cv/[slug]) instead of redirecting to MinIO storage directly
- Fix docker-compose: route backend/worker to internal MinIO URL (http://cvfs-minio:9000), remove MinIO from public network, parameterize all domain/env vars
- Add storage cleanup (MinIO artifact deletion) when a document is deleted
- Add docker-compose.standalone.yml for self-deployment without Traefik/dokploy
- Update .env.example with comprehensive self-deployment documentation
