Khalim Conn-Kowlessar 11393e54dc feat(modelling): price secondary-heating-removal from an off-catalogue overlay
The FE-owned `material.type` pgEnum cannot carry `secondary_heating_removal`,
so pricing it through the DB catalogue raises a DataError that poisons the
session — the modelling pipeline crashed on any property with a lodged
secondary heater unless the measure was excluded on the Scenario.

Realise the `ProductRepository` docstring's intent (DB catalogue today, a JSON
file for costs the ETL does not yet supply, behind the same port): add a
`CompositeProductRepository` that resolves an override source first, then the
catalogue. Checking the override first keeps that Measure Type away from the DB
entirely; every other type misses the override and falls through unchanged.

- off_catalogue_costs.json prices it at £270 flat per-dwelling — the legacy
  `Costs.heater_removal` ported to the new flat model (ADR-0028):
  (£25 + £200 baseline) x 1.2 VAT, for the single fixed secondary a cert lodges.
  Contingency (0.25) is joined from config, not the file.
- Wire the composite into PostgresUnitOfWork.product and run_modelling_e2e, so
  the first-run pipeline and the local runner both honour the overlay.
- Integration test: drop the unrealistic seeded secondary_heating_removal DB
  rows (the pgEnum can't hold the type) and assert it is JSON-sourced
  (material_id is None, cost £270) end-to-end through a real Unit of Work.
