Add staging gameplay smoke artifact output

+Smoke-suite skriver nu et gameplay-artifact som JSON under `/opt/wpp-staging/app/artifacts/smoke/` (kan overrides via `ARTIFACT_DIR`/`ARTIFACT_FILE`).
+
 Efter deploy validerer scriptet, at `DB_ENGINE` ikke er `django.db.backends.sqlite3` før migrations køres.
 
 Deploy-scriptet bruger en release-candidate mappe og promoverer først til `/opt/wpp-staging/app` efter succesfuld `migrate`. Det reducerer schema/code drift ved afbrudte deploys (issue #130) og understøtter release-readiness gate (issue #90).
