fix: reliable source upload, build cancel, WordPress port 80 default

- Replace port-forward/netcat PVC upload with kubectl cp for integrity
- Add build cancellation API and session cleanup; deploy catches cancel
- Default port 80 for WordPress, PHP, and Laravel on create
- Build progress modal with cancel; Helm/K8s adjustments for deployments
- Update build and kubernetes specs
