B17/E5: ингестия полевых данных КОНТУРа

- POST /operations/{id}/field-data/sync: тянет GET /api/v1/vector/areas-checked
  → идемпотентный upsert в areas_checked (dedupe по contour_area_id:
  geom/checked_at/result/coverage_pct/team_label, source=contour)
- GET /operations/{id}/areas-checked: теперь из локальной БД после sync
  (source=db), фолбэк на живой прокси КОНТУРа если пусто (source=contour/empty)
- миграция 011_b17_field_data: areas_checked +contour_area_id/team_label/source
  (+check ck_areas_checked_source)
- аудит field_data_sync; лог vector.contour field_sync_*
- фронт: кнопка «⟳ Синхронизировать полевые данные» в КОНТУР-панели,
  слой проверенных квадратов на карте (зелёный=clear ≥99.5%, жёлтый=partial)
