Goal

We lack displaying the current logged-in user information anywhere in the interface. We want to display the name of the current logged-in user in DX Core, similar to the way we do it in the dropdown on SaaS.

Design

• Instead of the "Edit user profile" text in the Profile dropdown, display the full name of the current user (can be several words or quite long).
• If full name is not available or empty, display the current username. 
• Instead of the "pencil" icon, display the User icon next to the name.

Check for both posibilities - external and mgnl users
