On a fresh ocr_cache volume /app/cache/.tmp does not exist yet. The mkdir
ensures the first Surya model download can proceed without ENOSPC on the
512 MB /tmp tmpfs. The find cleanup removes fragments left by docker-kill
mid-download, preventing cross-job ground-truth leakage.
Fixes#614. See ADR-021.

Adds ensure_blla_model.py which loads the blla segmentation model with
ketos on every container start. If the model is missing or in the legacy
PyTorch ZIP format (incompatible with ketos 7), it re-downloads the
correct CoreML protobuf model from Zenodo (DOI 10.5281/zenodo.14602569).
The Dockerfile now uses entrypoint.sh which runs this check before
starting uvicorn.
