Slice 3 of #1157. Persists a Plan and its Plan Measures to the live plan / recommendation tables via SQLModel mirrors (ADR-0017). - infrastructure/postgres/plan_table.py: PlanRow (`plan`) + RecommendationRow (`recommendation`) mirrors. RecommendationRow adds the new `plan_id` FK (ON DELETE CASCADE) linking each Plan Measure to its Plan, replacing the plan_recommendations m2m for new writes. from_domain mappers convert CO2 kg → tonnes to match the live column contract and derive post_epc_rating from the rounded SAP. Only the impact + cost + identity columns the tracer fills are declared; energy/bill, U-value, valuation, labour, plan_type are left to later slices. - PlanRepository port + PlanPostgresRepository.save(plan, *, property_id, scenario_id, portfolio_id, is_default) -> plan id. Idempotent replace: deleting the Plan cascades to its recommendation rows via plan_id, so a re-run overwrites (ADR-0012). No commit — the UoW owns the transaction. 2 tests (persist + idempotent re-run); pyright strict clean; 73 pass across repositories/modelling/orchestration with no regressions.
