Open External Links in a New Tab

还没有人认领这个 Issue。

Currently, when users click on external links within the application, they open in the same browser tab. This causes users to navigate away from the application entirely, which is interrupting workflow and negatively impact user experience.

**Expected Behavior**
External links should open in a new browser tab (e.g., using target="_blank" with appropriate security attributes like rel="noopener noreferrer"). This allows users to:
- Keep the application open in the original tab.
- Easily return to their previous context.
- Avoid losing unsaved progress or navigation state.

**Current Behavior**
All links (including external links) open in the same tab, replacing the current application view.

**Proposed Solution**
Update external anchor elements to open in a new tab by default.

**Additional Context**
Opening external links in a new tab is a common UX pattern in web applications, especially when linking to documentation or external references.

首先定位应用程序中的外部锚元素，并将其与保留在站点内的链接进行比较。在浏览器中验证外部链接会在单独的标签页中打开，而内部链接保留其现有行为，并确认在新标签页中打开的链接包含所请求的安全属性。
