FE Cypress tests for MenuBar navigation

[CCirbo]

Description

We need a new Cypress test file to cover all navigation functionality in the MenuBar, including dropdown menus and direct links. This test will make sure that every link or menu item takes the user to the correct page and that the expected content appears.

By centralizing these tests, we’ll have one place to verify the MenuBar works as intended now and as it evolves.

Tasks
• Set up a new Cypress test file: menu_bar_navigation_spec.js.
• Write tests for all dropdown menu options.
• Write tests for icons or direct links in the MenuBar.
• Confirm both URL changes and correct page content.
• Keep the tests clean and reusable for future updates.
