NPM retires audit endpoint; breaks pnpm audit

Getting messages at 7am that whole CI broke over night, tests and builds are dead, developers can't run install anymore. And as in any enterprise, everyone looks at the proxy, what could be wrong with it that it blocks the audit endpoint.

Posting this here just in case it saves someone time trying to figure out what's going on with `pnpm audit` (and why their CI might be failing, etc).
