feat(tradein/domclick): enrich Layer A SERP parser — description, repair-inference, minhash, seller
Capture extra bff-search fields in _map_item (verified live):
- description → ScrapedLot.description + infer_repair_state_from_text → repair_state
(DomClick search has no renovation-enum; text inference like cian #622)
- sha1 description_minhash (cross-source dedup)
- agency_name from seller (defensive str|dict)
- raw_payload: is_sber_collateral, has_discount, discount_value, duplicates_offer_count, seller
Additive only; existing Layer A behavior unchanged. Deep card detail (renovation-enum,
wallType, full price-history, owners_count) is card-only = QRATOR-blocked on prod proxy
→ separate effort (needs dedicated residential IP).
