[Helen-Sen]

What feature?

Create end-to-end tests for an existing user to validate key functionalities of the web application. The test should verify the ability to sig in and navigate through core pages (AI Assistant, My Tasks, My Wheel, Settings, Profile). It should check the presence of the sidebar and its buttons, as well as the avatar and username in the header. Additionally, it should verify that each page's title and main components are correctly displayed and functional.
