C2(jobsync): impl — fix entrypoint cd /app for nix container

The nix container has no /app directory — the app lives at
/nix/store/<hash>/app/ and the container's WorkingDir is set
to that path. Remove the cd /app that caused @prisma/engines
to not be found.

Also add jobsync to service-versions.yaml.
