## Description Closes: #53378 React app plugins can register a relative `bundle_url`. In UI dev mode, the Airflow HTML document is served by the API server, while the React UI modules are loaded from the Vite dev server. Because of that, `import(reactApp.bundle_url)` resolved relative plugin bundle URLs against the Vite origin instead of the Airflow API server origin. This changes the React plugin loader to resolve `bundle_url` against `document.baseURI` before dynamically importing it. Absolute bundle URLs are preserved, and relative bundle URLs now load from the Airflow document/API server base URL. ## Testing Tested manually with an Astronomer-style React app plugin using a relative `bundle_url`. ( astronomer-style react app docs : https://www.astronomer.io/docs/learn/using-airflow-plugins ) I created a temporary test React app plugin (`/simple-react-app/my-app.js`) with a relative `bundle_url` and used it to verify the behavior in UI dev mode. Before the change, `/simple-react-app/my-app.js` was requested from the Vite dev server at `http://localhost:5173/...` and returned the Vite fallback HTML instead of the plugin JavaScript bundle.

The plugin JavaScript loaded and the React plugin rendered successfully.
