Update NodeJS backend dependencies.

trev-dev commented 4 months ago

Jira: HD-26946

The goal of this pull request is to update the NodeJS backend and its dependencies. Due to some of the updates being incompatible with CommonJS modules, I opted to refactor the backend into the ESM (EcmaScript Module) format. This is the standard for JavaScript, whereas CJS was more of a node/webpack/bundler thing.

Breaking changes for nats and passport have been addressed as well. Check the commit messages, I tried to keep things granular.

Jest was also dropped in favor of Vitest. Vitest is actually prepared to test ESM files. This change removed a great deal of bloat from the dependency tree and sped up tests a great deal.
