* Implement Mastodon-compatible roles
- `Account.role` should only be available through verify_credentials for checking current user's permissions
- `Account.role` now carries a Mastodon-compatible permissions bitmap and a marker for whether it should be shown to the public
- `Account.roles` added for *public* display roles (undocumented but stable since Mastodon 4.1)
- Web template now uses only public display roles (no user-visible change here, we already special-cased the `user` role)
* Handle verify_credentials case for default role
* Update JSON exact-match tests
* Address review comments
* Add blocks bit to admin permissions bitmap
* update to use webp for thumbnails
* bump webp quality up to 40% from 12% (it's a bit different to jpeg quality setting)
* update to use yuva colorspace, and use thumbnail=n=10 to select frame
* fix missing comma in ffmpeg args
* add links to appropriate ffmpeg docs
* update tests
* add file size tests for thumbnails
