Final slice of ADR-0012: collapse the per-property read round-trips a batch made (Baseline hydrated ~8 queries x 30 properties one at a time) into a handful of per-table IN queries. - EpcPostgresRepository: extracted a shared `_compose(rows)` from `get` (the windows + floor-dim fetches are now passed in, not fetched inline), so both `get` and the new `get_for_properties(property_ids)` build EpcPropertyData from pre-fetched rows. `get_for_properties` fetches each child table once (`WHERE epc_property_id IN ...`), groups in memory, and composes — load-whole per ADR-0002. - PropertyRepository.get_many(property_ids) -> Properties: one query for the property rows + one bulk EPC hydration, composed in input order. - BaselineOrchestrator / IngestionOrchestrator read the batch via get_many instead of N x get. - Ports + fakes gain the bulk methods. The #1129 round-trip fidelity test stays green (the compose extraction is behaviour-preserving). New tests: bulk hydration correctness + round-trips are constant w.r.t. batch size (one-per-table, proven by query count). 123 pass; pyright strict clean; AAA.
