fix: stop logging during unit tests

our logs add a lot of noise and don't really contribute to anything when running "npm run test:unit".
this commit turns off logs during that context using an envrionment variable NODE_ENV.
anything else should be unaffected.

"fix" instead of "chore" because this commit changes actual production code and I want it to be treated as such.
