bot-backend 52fc920507 fix(tradein/domclick): rewrite dead scraper to BFF JSON API + honest status (#1846, #1968) 
Old HTML scraper dead: /search?city_id retired in DomClick redesign + VPS IP
QRATOR-banned (prod domclick_city_sweep reported done/0 every run). New path:

- GET bff-search-web.domclick.ru/api/offers/v1 + count/v1 via
  BrowserFetcher(source="domclick") -> generic provider -> shared mobile proxy
  -> bypasses QRATOR (prod-verified live: 20 items returned, no block).
- Sweeps 6 room buckets (st/1/2/3/4/5+); recursive binary price-split for
  oversized buckets (rooms=2 ~2215 > offset cap 2000); count/v1 sizes buckets.
- Maps SERP JSON -> ScrapedLot with lat/lon at ~100% (closes avito 54% NULL-lat
  gap); per-card EKB geo-guard.
- Honest status (#1968): QRATOR block OR fetch errors with 0 lots -> mark_failed,
  not mark_done. Parse failures are per-page resilient (break bucket, keep partial
  lots) so a transient bad page never aborts the whole sweep.
- Schedule shipped DORMANT (enabled=false, pages=100) via
  138_domclick_bff_rewrite_schedule.sql; operator enables after prod smoke.

42 scraper tests (price-split boundaries, parse-error resilience, honest status);
full backend suite green; ruff clean. Layer B (detail renovation/wallType/
priceHistory) deferred to #1846 follow-up.
