VITE_SENTRY_DSN is a Vite build-time variable baked into the JS bundle.
Without an ARG/ENV in the Dockerfile build stage and a build.args entry in
docker-compose.prod.yml, the SDK initialised with enabled=false regardless
of the Gitea secret value.
- frontend/Dockerfile: add ARG VITE_SENTRY_DSN + ENV before npm run build
- docker-compose.prod.yml: add build.args.VITE_SENTRY_DSN with empty fallback
- nightly.yml: write VITE_SENTRY_DSN secret into .env.staging
Requires Gitea secret VITE_SENTRY_DSN to be set to the GlitchTip project #1 DSN.
