Khalim Conn-Kowlessar ea4534f3af feat(modelling): system-built walls take EWI+IWI (blocked on basement-code fix)
System-built (precast/no-fines concrete) takes both solid-wall Options like
solid brick (ADR-0019), keyed on `wall_construction == 6` (WALL_SYSTEM_BUILT,
Elmhurst `SY`). A basement-suitability guard (`main_wall_is_basement`) is added
since a below-ground basement wall is never EWI/IWI-suitable.

This is currently inert: `B Basement wall` also maps to 6 (mapper.py:2100) and
`main_wall_is_basement` is derived as `wall_construction == 6`, so every code-6
wall reads as basement and is guarded out — the live cohort is unchanged. The
system-built EWI/IWI cascade pin is committed as a strict-xfail tripwire that
flips green the moment the calculator disambiguates system-built from basement
(MAIN wall_construction==6 with main_wall_is_basement False). `wall_construction
== 8` is Park home, not system-built — not keyed.
