Description
We need to add a waterfall visualization mode to local explanations in Shapash.
Today, local_plot mainly supports contribution bars, but we need a cumulative view that starts from a baseline and ends at the final prediction. This should make explanations easier to read in both regression and classification contexts.
The feature should also include configurable x-axis start behavior in waterfall mode (manual value and auto mode), and consistent explainer-agnostic wording in labels/tooltips.
