Subject: [PATCH 1/2] Use sparse checkout and targeted LFS fetch for
 HuggingFace model cloning

Replace bare `git lfs pull` (which downloads all LFS files including
duplicate .bin weights) with sparse checkout + targeted LFS fetch.
This prevents hanging on large models by excluding .bin/.gguf/.onnx
files, adding progress output, retry logic, and concurrent transfer
configuration. Falls back to .bin if no safetensors are found.

Subject: [PATCH 2/2] Fix FIPS selftest crash by pinning opencv-python-headless
 to 4.12.0.88

opencv-python-headless >=4.13 bundles a FIPS-enabled OpenSSL 1.1.1k
from CentOS/RHEL. On FIPS-enabled HPC hosts (where Singularity exposes
/proc/sys/crypto/fips_enabled=1), this bundled library triggers a fatal
FIPS selftest failure at import time, crashing vllm serve.

Pin to 4.12.0.88 which does not bundle OpenSSL.

Also remove ineffective FIPS workarounds from both containers:
- OPENSSL_CONF=/dev/null (targeted system OpenSSL 3.0.2, not the culprit)
- OPENSSL_FORCE_FIPS_MODE=0 (not a real OpenSSL variable)
- apt-get reinstall libssl-dev openssl (wrong library)
- pip rebuild cryptography from source (unnecessary)
