os.environ.get(key, default) returns "" when the key exists but is blank —
the default is only used when the key is absent. The or-fallback treats both
absence and blank values as "use the default".

With --no-create-home, os.path.expanduser("~") resolves to "/" causing
kraken get to write to /.local/share/htrmopo. Replace with
os.environ.get("HTRMOPO_DIR", "/app/models/.htrmopo") so the path is
explicit and override-friendly without a home directory.
Adds two tests verifying env-var resolution and ~-free default.

- _model_is_loadable: narrow bare except to (RuntimeError, OSError, ValueError)
with DEBUG-level fallback for unexpected exceptions — prevents silent masking
of missing kraken install or AttributeError on vgsl
- _run_segtrain: replace bare except:pass with log.warning so height-check
fallback is visible in container logs
- New test_ensure_blla_model.py: covers model-OK early return, incompatible
model rename+replace, and missing model download paths
