Bill / EnergyBreakdown / BillDerivation / sap_fuel were under domain/property_baseline/ only because Baseline was built first. The Modelling stage now needs them too, so move them (and their tests) to a neutral domain/billing/ — Fuel/FuelRates already live in the shared domain/fuel_rates/. Avoids a modelling -> property_baseline cross-stage import and a package name that wrongly implies ownership (ADR-0011, ADR-0014 amendment). Pure git mv + import rewrite across 10 files; 40 billing/baseline/repo tests pass, pyright strict clean. CONTEXT.md Bill Derivation location updated.
