Open External Links in a New Tab

Ninguém assumiu esta issue ainda.

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.

Comece localizando os elementos de âncora externos na aplicação e compare-os com os links que permanecem dentro do site. Verifique em um navegador se os links externos são abertos em uma aba separada, enquanto os links internos mantêm seu comportamento existente, e confirme que os links que abrem uma nova aba incluem os atributos de segurança solicitados.
