for *some reason*, coravel locks a persistent job queue behind a paywall. this means that if the server ever crashes, all pending jobs are lost. this is... not good, so we're switching to hangfire for that instead. coravel is still used for emails, though. BREAKING CHANGE: Foxnouns.NET now requires Redis to work. the EFCore storage for hangfire doesn't work well enough, unfortunately.
