feat(scrapers): search_by_quarter orchestrator + QuarterDump (#94 pt.2/4)

Sprint 1.1 item #1 из плана #94 part 2. Foundation для PKK harvest pipeline —
1 vacuum (search) + N layer fetches → comprehensive snapshot всех NSPD данных
в пределах квартала. Базис для G1 #28 ПЗЗ, G3 #30 ЗОУИТ, P2 #46 neighbors,
E1 #51 parcels backfill, #96 ЕГРН помещения.

Backend (nspd_client.py):
- New QuarterDump frozen dataclass (slots=True): quarter + per-layer feature
  lists (parcels/buildings/territorial_zones/red_lines/engineering + zouit
  dict + risks dict) + bbox_3857 + layers_fetched (immutable tuple) +
  fetched_at_utc + total_features property.
- New NSPDClient.search_by_quarter(quarter_cad, include_zouit=True,
  include_risks=False): search → bbox → bulk fetch per layer phase.
  Cost 6/11/22 requests.
- New _geojson_bbox_3857() module-level helper — recursive coord walker.
- Class constants QUARTER_CORE_LAYERS / QUARTER_ZOUIT_LAYERS /
  QUARTER_RISK_LAYERS.

Empty-quarter (NSPD не нашёл cad): quarter=None, bbox=None, all lists empty,
zouit/risks dicts populated с пустыми lists (структурно стабильно),
layers_fetched=('search',).

Tests: +12 tests (31 total, no network).

Code review (code-reviewer pre-push): MINOR, fixed 3 of 5:
- datetime import → module-level
- layers_fetched → tuple[str, ...] (immutable in frozen dataclass)
- docstring clarified empty-quarter semantics
Bonus: ruff UP038 isinstance tuple → union syntax.

Part of #94. Sprint 1.1: 4 PRs total. Next: migration → Celery → integration.
