Khalim Conn-Kowlessar 6bb1843be6 Map PasHub boiler PCDB product_id to main_heating_index_number
`_map_sap_heating` left `main_heating_index_number` None, so the
calculator fell to a generic Table-4b seasonal efficiency instead of the
actual appliance. The site note lodges the boiler by its PCDB `product_id`
(and `summer_efficiency` is always 0), and those ids resolve directly in
the calculator's PCDB (`gas_oil_boiler_record`) — so carrying `product_id`
onto `main_heating_index_number` gives the real SEDBUK efficiency.

Gated on `product_id > 0` (0 = no product lodged → stays None; the
calculator keeps its default). `main_heating_category`/`sap_main_heating_code`
were evaluated and add nothing measurable — the PCDB index alone is the
efficiency source.

Guinness GMCA cohort: within-0.5 12.9% -> 13.4%, MAE 2.657 -> 2.621, no
regression (harness still 206-xfail, no new hard failures).

Closes #1563
