Jun-te Kim 28b72fc67c Normalize RdSAP hot-water demand (WWHRS rooms) on the degraded 17.0/19.0 paths
PRD #1385, shower/WWHRS family. The 17.0 and 19.0 API mappers left
sap_heating.number_baths / mixer_shower_count as None, so the water-heating
demand (cert_to_inputs) fell back to defaults instead of the lodged bath/shower
room counts. Derive them from schema.sap_heating.instantaneous_wwhrs, mirroring
the 17.1/18.0/20.0 paths:

  number_baths       = rooms_with_bath_and_or_shower + rooms_with_bath_and_mixer_shower
  mixer_shower_count = rooms_with_mixer_shower_no_bath + rooms_with_bath_and_mixer_shower

Guarded on instantaneous_wwhrs is not None (Optional in the schema), like 17.1.
Counts, same meaning across the reduced-field family.

Verification: new test 2 passed; test_mapper_corpus 6002 passed; SAP-accuracy /
RealCertExpectation regressions pass; pyright unchanged (39 -> 39, pre-existing).
