Missing lockfile package-lock.json or yarn.lock

The repo doesn't contain a lockfile file such as package-lock.json (when npm used) or yarn.lock (when yarn used), which enable reproducible-builds as the same versions can be used when rebuilding the app by using npm ci command which currently fail with error.

fix: include lockfile in the repo, and ensure app compilation work when npm ci or yarn install --frozen-lockfile is used to install deps (needed for reproducible deps installation)
