Last commit before separate repos work

This marks the last commit since the frontend broke off from the
combined frontend/backend repository.

After this point, commits were made to the separated repo.

This is an exact record of the command used to separate the repos:
../git-filter-repo --path package.json --path tsconfig.json --path yarn.lock --path .prettierrc.js --path .eslintrc.json --path-regex '^app\/javascript\/(?:(?<!packs\/).)*$' --path-rename app/javascript/:src/ --path .gitignore

This was run with the git filter repo
(https://github.com/newren/git-filter-repo) script, which was located in
the directory above ("..") in this case.
The current working directory was a freshly cloned copy of the `console`
repository.
