fix(documents) : exclude path from collection to prevent OOM, lazy-load on demand

The path field contains base64 data URIs that can be several MB each.
Loading 200 documents at once exceeded the 128MB PHP memory limit.
Now the collection endpoint uses document:list group (without path)
and the frontend fetches the full document on demand when the user
clicks download or preview.
