lekss361 e5fb209ced feat(tradein): scraper_settings -- live-config request delay for Yandex scrapers + admin triggers 
Backend foundation for the Yandex admin scraper page (UI follows in next PR).

scraper_settings (mig 053):
- New table source PK + request_delay_sec numeric(5,2) + updated_at + description
- Seeded with row 'yandex' = 5.0s (umbrella key for all 4 Yandex scrapers)

scraper_settings.py (new):
- get_scraper_delay(source) -> float, with 60s in-process cache + DB fallback
- Yandex sub-scrapers (yandex_detail / yandex_newbuilding / yandex_valuation)
  resolve to umbrella 'yandex' key via _KEY_ALIASES
- invalidate_cache(source | None) for admin PUT side-effect
- Deferred SessionLocal import (_open_session helper) for unit-test compat

4 Yandex scrapers wired to load delay at __init__:
- yandex_realty.py / yandex_detail.py / yandex_newbuilding.py / yandex_valuation.py
- Class default bumped to 5.0; instance value overridden via get_scraper_delay(self.name)

admin.py -- 5 new endpoints:
- GET    /scraper-settings           list[ScraperSetting]
- PUT    /scraper-settings/{source}  upsert + invalidate_cache
- POST   /scrape/yandex-detail       offer_url= -> detail snapshot
- POST   /scrape/yandex-newbuilding  slug=, id=, city=ekaterinburg -> JK snapshot
- POST   /scrape/yandex-valuation    address=, offer_category=, offer_type=, page= -> house meta

Tests: 10 + 4 = 14 new unit tests (loader cache/alias/error paths + scraper wiring).
Ruff clean.
