refactor(tradein/admin): debug sweep endpoints на kit orchestration (#2397 slice A)

Мигрирует 5 admin debug-роутов с legacy app.services.scrape_pipeline на
scraper_kit.orchestration.pipeline (эпик #2277 decommission, umbrella #2397):

- POST /scrape/avito-city-sweep -> run_avito_city_sweep
- POST /scrape/cian-city-sweep -> run_cian_city_sweep
- POST /scrape/cian-full-load -> run_cian_full_load
- POST /scrape/yandex-city-sweep -> run_yandex_city_sweep
- POST /scrape/yandex-full-load -> run_yandex_full_load

DI-паттерн зеркалит app.scheduler_main._run_kit_scheduler /
scraper_kit.orchestration.scheduler._job_* (уже используется в этом же файле
для Group A #2305 debug-роутов): config=RealScraperConfig(),
matcher=RealMatcherAdapter(), proxy_provider=_kit_proxy_provider() для всех
пяти + enrichment=RealEnrichmentJobs() там, где kit-сигнатура его требует
(avito_city_sweep, yandex_city_sweep, yandex_full_load — cian-варианты
enrichment не принимают). shutdown_requested не прокидывается — у admin
BackgroundTasks нет SIGTERM-drain семантики, дефолт kit (lambda: False)
эквивалентен прежнему поведению.

Разблокирует финальное удаление зависимости admin.py от scrape_pipeline.py.
Production-scheduler (app/services/scheduler.py, USE_KIT_SCHEDULER=False
ship-dark) остаётся на legacy — это отдельный, более крупный шаг миграции
SERP-оркестрации.
