feat(tradein): yandex_realty.py — DOM SERP refactor (vtorichka, 23 cards/page)
Replace dead JSON-state extraction (Yandex moved to chunked/ephemeral state
post-hydration) with selectolax DOM parsing using helpers from PR #456.
Changes:
- New URL: /{city}/kupit/kvartira/vtorichniy-rynok/?page=N (path-based, no geo)
- Selector: [data-test="OffersSerpItem"] x ~23 per page
- Per-card extraction: offer_id (URL regex), title (rooms/area/floor regex),
price/ppm2 (regex + parse_rub), bargain flag, publish_date (parse_ru_date),
street address, photos (avatars.mds.yandex domain filter + size upgrade),
newbuilding linkage (house_source='yandex_realty_nb' + house_ext_id)
- ScrapedLot mapping: lat/lon=None (no coords on SERP — geocode-missing
fills later), listing_segment="vtorichka"
- Pagination: fetch_around_multi_room -> up to MAX_PAGES=3 pages, dedup by
source_id. **kwargs swallow keeps old rooms/sort/pages callers compat.
- Preserved: BaseScraper interface, name="yandex" (matches existing rows +
avoids breaking dedup_hash; Wave 5 conflict resolution can alias if needed),
request_delay_sec=5.0, sleep_between_requests, tenacity retry.
Tests: 10 unit tests against hand-crafted fixture HTML (single card / studio /
no-price / empty page / multi-card / URL builder / city override) — all pass.
Ruff clean.
