feat: production-ready deployment with multi-language UI

- Add multi-language support (NL, AR, EN) with RTL
- Improve health checks (SSL-tolerant, multi-endpoint)
- Add DELETE /api/stack/:name for cleanup
- Add persistent storage (portal-ai-workspace-{name})
- Improve rollback (delete domain, app, project)
- Increase SSE timeout to 255s
- Add deployment strategy documentation
