Move all Databricks notebooks out of nested notebooks/ subdirectories to sit alongside their sibling helper modules. This eliminates the %cd .. hacks that were needed to import from parent directories and simplifies the project layout for a data science workflow. Moves: - training/notebooks/*.py → training/*.py - validation/notebooks/ModelValidation.py → validation/ModelValidation.py - deployment/*/notebooks/*.py → deployment/*/*.py - feature_engineering/notebooks/*.py → feature_engineering/*.py - monitoring/notebooks/*.py → monitoring/*.py Updates all resource YAMLs, update_layout.tmpl, and README references.

Databricks bundle deployments set the notebook CWD correctly, so the notebook_path/%cd $notebook_path pattern is unnecessary. Sibling imports work naturally after the flatten-notebooks change. Also inlines the trivial get_deployed_model_stage_for_env helper (a dict lookup) to eliminate cross-directory sys.path.append in deploy.py and BatchInference.py. Co-authored-by: Isaac

- Bump mlflow to >=3.1, unpin pandas and numpy - Update MlflowClient imports (from mlflow import MlflowClient) - Remove registry_uri="databricks-uc" and set_registry_uri calls (no longer needed in MLflow 3.x with Unity Catalog) - Fix empty run_id bug in ModelValidation (MLflow 3.x UC model versions may have empty run_id) - Replace importlib/getattr dynamic loading of validation config with direct imports from validation.py - Remove test_mlp.py (mlflow.recipes removed in MLflow 3.x) - Clean up CI workflow secrets Co-authored-by: Isaac
