097_index_hygiene.sql de-partialized 5 listings indexes on the false premise
that is_active=100% true. 104_index_hygiene_geom_dedup.sql acknowledged the
premise is stale (49% active on prod, 2026-06-13) but only cleaned up the
redundant geom duplicate, leaving 3 composite indexes full.
Restore WHERE is_active=true on the composite hot-path indexes:
- listings_active_filter_idx (rooms, price_rub, area_m2, scraped_at DESC)
- listings_house_price_idx (house_id_fk, price_rub)
- listings_rooms_area_idx (rooms, area_m2)
Excluded: listings_geom_active_idx (dropped by 104, listings_geom_idx covers it),
listings_scraped_desc_idx (not in issue #1398 suggested fix scope).
CONCURRENTLY not used — migration runner wraps in BEGIN/COMMIT (see 117 note).
