CD onboarding flow - Login/logout

[IMHieuVo]

Platform Oppia Web

Describe the request When a logged-out user visits the contributor dashboard (CD) page at Oppia.org, they see a "you are logged out, please log in" screen. The aim of this project is to design the "you are logged out, please log in" experience for the CD.

Context for the request

• This functionality already exists, but hasn't really gone through a design process and should be audited. If the existing functionality is fine, it's OK to close this issue,

Actually, I'm going to close this for now since it's not a major need. We can revisit later if it proves to be a problem in the onboarding process.

Please feel free to comment/reopen if you disagree with this. Thanks! /cc @IMHieuVo @rflore
