Enhancements on user profile

What's the problem and how can it be solved?

Some Enhancements for the user profile

• Add field for "first name" and "last name" next to username and show this name on UI
• On Header show first name (if exists, otherwise username) and profile picture on the top right of the header and make it a dropdown menu with links to "Edit Profile" and "Logout". This also saves space on the Header.
