perf(tradein): index hygiene — drop dup/redundant + de-partial is_active (#730 )

Deterministic subset of TradeinDb_Audit_May30. Migration 097 (BEGIN/COMMIT,
IF EXISTS, idempotent):
- drop 4 exact-duplicate indexes (houses_kadastr_idx2, houses_addr_fp_idx,
  listings_scraped_idx, listing_sources_price_divergence_idx) + redundant
  houses_source_ext_idx (covered by UNIQUE constraint backing index)
- de-partial 5 listings WHERE is_active=true indexes (is_active 100% true →
  full index strictly covers partial, no plan regression)

87-unused sweep DEFERRED — needs a live pg_stat_user_indexes snapshot.
