## PR-Codex overview
This PR enhances the `Page` function in `page.tsx` to handle `searchParams`, allowing for an import URL to trigger a redirect when present.

### Detailed summary
- Added `searchParams` to the `Page` function's props.
- Used `Promise.all` to await both `params` and `searchParams`.
- Implemented a redirect to an import URL if `searchParams.importUrl` is provided.
