User Login

Value Proposition

As a family member,

I want to be able to log in to the app,

so that I can access my personalized dashboard, view my tasks, and manage family-related activities securely.

There is a Log in button on the top right in the header, and if user isn't signed in, there is a message "You are not logged in! Please log in." on every page.
Clicking the Log in button shows GitHub login page.
After the user signs in, their avatar and username should appear in the top right corner and the whole user specific content from the homepage is visible.
Clicking the avatar and username navigates user to their profile page.
On the user's profile page, there should be a "Log out" button.
Clicking on "Log out" button signs the user out.
