Adds `"NON": 30` to `_ELMHURST_MAIN_HEATING_EES_TO_FUEL_CODE` so the mapper can derive the main heating fuel for the Elmhurst "no main heating system" lodging (§14.0 Main Heating EES = NON + SAP code 699 + §14.1 Heating Type = None). SAP 10.2 §A.2.2: "When no main heating system is identified, the calculation is for the assumed system consisting of portable electric heaters." Routes the fuel to Table 32 standard-electricity code 30 (tariff resolved separately from `meter_type` per `_rdsap_tariff`). Pre-slice the cascade raised `MissingMainFuelType` per S0380.132. Post-slice the cascade closes most of the way: no system: ΔSAP_c +1.18, Δcost −£27, ΔCO2 −50, ΔPE −562 The residuals are cascade-side (likely §A.2.2 portable-electric efficiency / responsiveness / control-type defaults differ slightly from Elmhurst) — pinned at observed values as forcing function for follow-up. Moves `no system` out of `_BLOCKED_BY_MISSING_MAIN_FUEL_TYPE` into `_EXPECTATIONS`. Blocked tier now: 5 community-heating variants. Tests: - test_elmhurst_main_heating_ees_maps_no_system_code_to_electricity - corpus pin: no system expected residuals at observed values 916 pass / 0 fail.
