feat(tradein/estimator): switch core valuation call sites to scraper_kit (#2337)
Group E4 (final, highest-risk step of scraper_kit migration epic #2277):
estimator.py and house_imv_backfill.py's avito_imv/cian_valuation/
yandex_valuation call sites now import from scraper_kit.providers.* instead
of app.services.scrapers.*, following the exact wiring proven safe by E1/E2/E3
(#2334/#2335/#2336):

- estimator.py's avito IMV (_get_or_fetch_imv_cached, both call sites) and
  house_imv_backfill.py's _process_one_house: add config=RealScraperConfig()
  — kit's evaluate_via_imv silently drops the configured proxy without it.
- estimator.py's cian valuation (Stage 9): add config=RealScraperConfig() —
  mandatory kwarg on the kit function (TypeError if omitted).
- estimator.py's yandex valuation: add config=RealScraperConfig() (mandatory)
  and delay_provider=get_scraper_delay — without it kit silently falls back
  to a hardcoded 5.0s throttle instead of the DB-configured anti-ban delay.
- All exception classes imported consistently from the same kit module as
  evaluate_via_imv (not just the function) — mixing legacy/kit exception
  classes would break `except IMVAddressNotFoundError` etc. via identity
  mismatch (caught by an existing test that assumed the legacy class,
  fixed alongside).

Observability: both cian_valuation and yandex_valuation graceful-degradation
except-blocks upgraded from logger.warning to logger.exception. GlitchTip's
LoggingIntegration listens at event_level=ERROR (main.py/scheduler_main.py) —
a WARNING never reaches GlitchTip as an event regardless of exc_info, so a
future config-wiring mistake at these call sites needs ERROR level to be
visible in monitoring.

house_imv_backfill.py: RealScraperConfig is imported lazily inside
_process_one_house (not at module level) to avoid a circular import —
app.services.scraper_adapters imports backfill_house_imv/
process_houses_imv_batch from this module at module level. Verified via
direct import in both orders plus a full `app.main` import.

Also fixes a stale docstring claiming process_houses_imv_batch is "not wired
into scheduler" — it is, via scrape_pipeline.py's run_avito_city_sweep.

Test updates: 2 pre-existing tests (test_backfill_wave2.py) mocked the legacy
IMVAddressNotFoundError/IMVEvaluation/IMVGeo classes, now updated to import
from scraper_kit to match the production exception identity. Added
config=/delay_provider= regression-guard asserts to the relevant estimator
and backfill tests, mirroring the existing #2306 cian_price_history pattern.

Legacy app/services/scrapers/{avito_imv,cian_valuation,yandex_valuation}.py
are untouched and still imported by cian_history_backfill.py's valuation
block (separately scoped, not touched here) — revert is a clean single-commit
revert, no schema/data migration involved.
