lekss361 925d7d15cc feat(tradein): search matview + indexes (Phase 3.1) ...

Multi-Source Integration Phase 3.1. Foundation for /api/v1/search p95 < 100ms
on 100K+ listings.

SQL 050_search_optimization.sql:
  - CREATE EXTENSION IF NOT EXISTS pg_trgm
  - ALTER listings ADD COLUMN tsv tsvector GENERATED ALWAYS AS (...) STORED
  - 10 indexes (geom GIST, composite, gin_trgm, GIN tsv, partial kadastr, ...)
  - CREATE MATERIALIZED VIEW listings_search_mv (per-listing aggregated across sources)
  - 5 matview indexes

Celery task tradein.refresh_search_matview:
  - REFRESH MATERIALIZED VIEW CONCURRENTLY listings_search_mv
  - Logged duration via logger.info
  - Beat schedule snippet (crontab hour=3, minute=0) in docstring — wiring to
    app/celery_app.py left to follow-up PR per main-session coordination.
