bug: UNAUTHORIZED displayed on homescreen

Every time an unauthenticated users loads the website we get the following error:

```
Failed to load resource: the server responded with a status of 401 (UNAUTHORIZED)
website.js:177

Start with apps/press/press/auth.py, especially the hook shown in the traceback, and inspect the request initiated near website.js:177 when the homescreen loads unauthenticated. Confirm which request returns 401 and ensure the homescreen no longer produces the unauthorized error for unauthenticated users.
