Adds whole-dwelling property_type/built_form to EpcSimulation (folded by
apply_simulations) and maps those override components. property_type drives
party-wall heat loss + ASHP/solar/wall eligibility, so a landlord correction now
moves both the SAP calc and the measure menu; built_form has no calculator
consumer today (feeds the ML transform). Written as the landlord text value
(park-home check is text-only). Refines ADR-0032 dec-4.

Extends WallType coverage to timber/stone/system-built/cob/park-home/curtain and
adds RoofType "Pitched, N mm loft insulation" -> roof_insulation_thickness. The
"(assumed) insulated"/"partial" wall states stay deferred (ambiguous code, needs
Elmhurst validation per ADR-0032); property_type/built_form carry no SAP weight.
