Multi-Source Integration Phase 1.1 thin-delta migrations. Gap audit showed 80%+ of planned schema already in 014/017/020/026/028/029/030/031 — this PR adds only the missing pieces: - 040 houses_extend: complex_id + avito_validated_at + cian_validated_at - 041 house_sources_noop: COMMENT aliases for ext_source/ext_id/matched_method - 042 listing_sources_price_divergence_idx: partial index for /search - 043 house_reviews_extend: likes column - 044 external_valuations_link: house_id/listing_id FKs + low/high price band - 045 house_placement_history_extend: source_confidence + notes + 3-col UNIQUE - 046 views: v_price_divergence + v_cross_source_health + v_data_quality All BEGIN/COMMIT, IF NOT EXISTS, FK ON DELETE CASCADE. Idempotent — safe re-apply on prod. Refs Master Plan sec 1, 4-8 + Cross_Source_Matching sec 2-4.
