Slice 3c.2. The OS Open-UPRN reference set is too large to host in Postgres, so it lives in S3 and is cached per-UPRN in the existing `property_details_spatial` table (ADR-0020). `PropertyDetailsSpatialRow` mirrors that table (uprn unique); `SpatialRepository` / `SpatialPostgresRepository` upsert one shared row per UPRN and read the planning protections back by UPRN (a null flag reads as unrestricted; absent UPRNs are omitted so the caller defaults them).
