[feature] proof of work scraper deterrence (#4043)
This adds a proof-of-work based scraper deterrence to GoToSocial's middleware stack on profile and status web pages. Heavily inspired by https://github.com/TecharoHQ/anubis, but massively stripped back for our own usecase.
Todo:
- ~~add configuration option so this is disabled by default~~
- ~~fix whatever weirdness is preventing this working with CSP (even in debug)~~
- ~~use our standard templating mechanism going through apiutil helper func~~
- ~~probably some absurdly small performance improvements to be made in pooling re-used hex encode / hash encode buffers~~ the web endpoints aren't as hot a path as API / ActivityPub, will leave as-is for now as it is already very minimal and well optimized
- ~~verify the cryptographic assumptions re: using a portion of token as challenge data~~ this isn't a serious application of cryptography, if it turns out to be a problem we'll fix it, but it definitely should not be easily possible to guess a SHA256 hash from the first 1/4 of it even if mathematically it might make it a bit easier
- ~~theme / make look nice??~~
- ~~add a spinner~~
- ~~add entry in example configuration~~
- ~~add documentation~~
