Could you edit the GitHub workflow so the linting works again?
Other than that, I don't see any issues but this is a pretty big PR. Once it's merged if there are issues we can revert and fix them.

@btwj not sure if Dockerfile has to be updated since we hoisted some of the dependencies. Might need to add a command to generate the prisma client too. (npm run db-generate)
