-- Fix ChatOllama._get_ls_params to honor the per-call `model` kwarg override.
--
-- langchain-tests 1.1.9 expects ls_model_name to reflect kwargs['model']
-- (e.g. from bind() or invoke(model=...)), but the 1.1.0 release always
-- used the constructor's self.model, causing test_standard_params_model_override
-- to fail.
