Add SearXNG as configurable search provider

- Add SearXNG entry to searchproviders.yaml
- Add searx_url setting for user-configurable instance URL
- Modify Search::providerDetails() to inject user's SearXNG URL
- Add English translations for new setting and provider

SearXNG is a self-hosted metasearch engine, so unlike other providers
the URL cannot be hardcoded. This implementation allows users to
configure their instance URL in settings, which is then dynamically
injected when performing searches.
