User auth bug fixed

Fixed a bug that impacted all users since the server migration.

Bug: Many users were unable to login, or could not post due to a cache issue.

Reason: Our new server cached responses more heavily to speed up the site and app. As a result, it also cached a few endpoints that it is not supposed to. This causes issues with posting, logging in, chat etc. for many users.

Fix: We've relaxed the caching rules to be less aggressive so it doesn't falsely cache responses it is not supposed to.

Thank you everyone for your patience this week, a lot has been going on🙏
