About issue #10140
In version 0.20.1, we implemented the generation of new node through
mouse drag and drop. If we could create a workflow module like in Coze,
where there is not only a dropdown menu but also an intermediate node
(placeholder node) after the drag and drop is completed, this could
improve the user experience.

### What problem does this PR solve?
This PR integrates SearXNG as a new search tool for Agents. It adds
corresponding form/config UI on the frontend and a new tool
implementation on the backend, enabling aggregated web searches via a
self-hosted SearXNG instance within chats/workflows. It also adds
multilingual copy to support internationalized presentation and
configuration guidance.

[web/src/locales/en.ts](cci:7://file:///c:/Users/ruy_x/Work/CRSC/2025/Software_Development/2025.8/ragflow-pr/ragflow/web/src/locales/en.ts:0:0-0:0):
