♻️ refactor(home): build serverAddress using ${window.location.origin}

Replace the fallback assignment of serverAddress in `web/src/pages/Home/index.jsx`
to use a template literal for `window.location.origin`.

- Aligns with the preferred style for constructing base URLs
- Keeps formatting consistent across the app
- No functional changes; behavior remains the same
- Lint passes with no new warnings or errors
