fix(ci): contourner upload-artifact Gitea — build sur docker-host

L'étape Upload web artifact échouait systématiquement (stockage
artefacts Gitea instable). Le déploiement ne passera plus par
upload/download-artifact entre runners.

- CI ubuntu : lint + tests + build (validation uniquement)
- Deploy docker-host : npm ci + build + tar local /tmp/web-artifact.tgz
- deploy-prod.sh consomme l'artefact local, sans download-artifact
