The Rebaseliner is the assemble-and-score step (ADR-0013 amendment); its
SapResult is the scored picture that Bill Derivation also prices (ADR-0014),
so rebaseline() now returns a RebaselineResult{effective, reason, sap_result}
instead of (Performance, reason). CalculatorRebaseliner sets sap_result on
both branches (the bill prices it whether lodged or calculated figures win);
StubRebaseliner returns sap_result=None (runs no calculator). Orchestrator
unpacks the result; the bill wiring lands in the next slice.
Also refreshes the stale ML-era docstrings in rebaseliner.py to the
assemble-and-score model (the calculator, not ML, is the rebaseliner
mechanism per ADR-0013).
