Day 34 - since independently-run production servers have been failing me for 34 days, every single day, DRASTIC changes to the API - return failure counts to that error path

A user on 0.18.1-rc6 on Lemmy.world reported an upvote error.

I think the API should have a counter of the error and that the API should return the count. If it isn't saved, fine, but maybe return system uptime on errors too.

This puts the power more in the hands of clients instead of server operators to know what is gong on internally with the Lemmy servers that are falling flat on their face performance-wise in the 0.18.1 era.
