feat: enhance SearxNG settings and improve loading indicators

- Added new search engines (qwant news, qwant images, qwant videos, mojeek images, mojeek news) to the default settings for better search results.
- Updated outgoing request settings by removing the decimal from `extra_proxy_timeout` for consistency.
- Integrated a `Spinner` component in `LayoutDataProvider` to improve loading feedback during chat deletion processes.
