fix(#231): switch search_by_quarter area layers to grid-walk dispatch (Sub-PR B)
- Add _GRID_WALK_LAYERS frozenset (territorial_zones, red_lines,
engineering_structures, zouit_*, risk_*)
- _fetch_layer dispatch: area layers → get_features_in_bbox_grid(grid_n=7,
step_m=50) [foundation из PR #247], EGRN layers (parcels, buildings) →
legacy get_features_in_bbox
- Enrich engineering_structures features с classified_kind через
classify_engineering_kind (PR #247 classifier)
- Per-layer logger.info heartbeat (method + count) для прогресса
- Bump harvest_quarter soft_time_limit 120 → 600s
(grid-walk: 11 layers × 49 cells × ~70ms ≈ 40s + retries margin)
- TestFetchLayerDispatch (3 tests): 34 passed, 1 skipped
Pre-push deep-code-reviewer: APPROVE (1 medium nit — opportunity_oopt не в
grid-walk, защищено через include_opportunity=False default; follow-up issue
рекомендован).
