Frontend not runnable – missing Git LFS objects

[sm-28601]

frontend/package.json is a Git LFS pointer, but git lfs fetch --all,
git lfs pull, and git lfs checkout do not download any data (0 B/s).
The pointer file remains, so npm install / npm run dev fail with EJSONPARSE.

This indicates the frontend LFS objects are not present in remote LFS storage.
As a result, the frontend cannot be run locally. Please upload the actual
frontend files to LFS or provide the frontend source.
