Description
Extract getEnvironmentConfig into its own module so the download Web Worker no longer imports React code transitively, fixing the Uncaught ReferenceError: window is not defined that prevented file downloads in dev mode. The worker imported fetchFileStream, which pulled getEnvironmentConfig from network.service/index.ts, and that barrel also imported notifyUserWithCooldown → notifications.service → react-hot-toast and React components.
In dev, Vite has no tree-shaking and injects the @react-refresh HMR prelude into any module that looks like React code, and that prelude references window, which doesn't exist inside a Web Worker, so the worker crashed at load time.
In production it didn't surface because Rollup tree-shakes the unused branch and there's no HMR prelude, but the coupling was fragile.
