### What problem does this PR solve?
This PR is related to
[#9961](https://github.com/infiniflow/ragflow/issues/9961).
In the Chat Settings screen, the textarea did not support scrolling when
the content grew longer than its visible area, which made it less
convenient to use.
Also, there was no Japanese placeholder text to guide users on what to
enter in the field.
This PR improves the user experience by:
- Adding `overflow-y-auto` to the textarea so that long content can be
scrolled smoothly.
- Introducing a placeholder (`メッセージを入力してください...`) to provide clearer
guidance for users.

### What has been considered
As an alternative solution, I explored replacing the textarea with the
existing `PromptEditor` component.
However, this approach triggered a `canvas not found.` alert.
The current implementation of `PromptEditor` internally attempts to
fetch **agent (canvas) information**, but in the Chat Settings screen no
such ID exists. As a result, the API call fails and the backend returns
`canvas not found.`.
One possible workaround would be to extend `PromptEditor` with a
**“disable variable picker” flag**, ensuring that plugins are not loaded
in contexts like Chat Settings. While feasible, this would have a
broader impact across the codebase.
Given these considerations, I decided to address the issue in a simpler
way by applying a Tailwind utility (`overflow-y-auto`). Since the UI
design is expected to change in the future, this solution is considered
sufficient for now.

### 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.
