Service worker scope

Based on the current [PWA example](https://github.com/DioxusLabs/dioxus/tree/662cf0d90261b8540796225b78913b620ea34a8f/examples/pwa), all static assets, including the JavaScript file containing the service worker code, are currently served from the `/assets` directory. Because of this, the service worker's scope is implicitly restricted to `/assets`, preventing it from controlling or caching requests outside that path. Notably, it cannot cache or intercept requests for the main WebAssembly application. This blocks use cases like full offline support.

Is there a workaround that allows the service worker to be served from `/` directly?
