Khalim Conn-Kowlessar 85d6f8468c feat(elmhurst-extractor): capture section 15.1 Immersion Heater (Dual/Single)
The Elmhurst Summary section 15.1 "Hot Water Cylinder" block lodges
"Immersion Heater: Dual" / "Single"; the extractor dropped it, so the
Summary path left immersion_heating_type = None while the API path already
captured it. Capturing it drives SAP Table 13's high-rate-fraction
DHW-cost split (RdSAP 10 section 10.5 p.54: 1 = dual, 2 = single) and
brings the two front-ends to parity.

Three-file change: WaterHeating.immersion_type field +
_extract_water_heating parse (scoped to the 15.1..15.2 slice) +
_elmhurst_immersion_type_code mapper (strict-raise on an unmapped label,
mirroring _elmhurst_cylinder_insulation_code).

Safe to land now that the preceding commit zeroes the high-rate fraction
for 18-/24-hour tariffs: the 20 solid-fuel corpus certs (solid fuel 4-11:
WHC 903 dual immersion, 18-hour meter, 110 L) carry a dual immersion, but
their 18-hour tariff bills 100% low-rate per Table 12a's 7-/10-hour scope
— so they stay EXACT instead of regressing to the 10-hour-column ~0.10.
7-/10-hour Summary immersion certs now correctly cost the Table 13
high-rate fraction instead of falling to the immersion=None 100%-low
default.

Regression gate green (3 pre-existing fails unrelated); API gauge
unchanged (Summary-path-only): 57.6% within 0.5, mean|err| 1.185.
