Add login information component

[jensren]

What: add the login information as seen in the top right corner:

(Note: there is no green box in the Figma, I added that to show what I mean by login component)

Right now, we cannot put it exactly there since the navbar is still horizontal at the top of the page. Instead, we can put the login under the navbar and move the login to the top after the navbar is moved to the side.

Why: after we implement logins, we will use this component to display the user data

How:

• Add a login component that is visible on the top right corner of every page, as shown in the screenshot. Login component should shift the page contents down (so the title is lower than the login, as in the screenshot). Login component can be just underneath the navbar for now
• Display the user's name, email, and profile picture
• If possible, use a Bootstrap component rather than writing custom styling. If you need to write custom styling, please write it with styled components rather than css modules
