feat(cadastre): NSPDBulkClient + schemas for bulk ingest (#168 PR2/5) (#170)
Add async NSPD client (nspd_bulk_client.py) with 3 new methods:
- search_by_quarter: REST /api/geoportal/v2/search/geoportal — snapshot 20 per cat + meta totals
- wms_feature_info: WMS GetFeatureInfo для grid-walk discovery
- list_objects_in_building: tab-group-data (Q3 deferred — код ready)
Rate limit: asyncio.Semaphore(3) + 0.05s jitter.
429 → exponential backoff 2→4→8s, max 3 retries.
403 (WAF) → raise immediately, no retry.
Pydantic schemas (nspd_bulk.py): NSPDBulkFeature, QuarterSnapshot, ObjectsListing
with extra='allow' to preserve unknown fields → raw_props JSONB downstream.
15 unit tests + 4 e2e (real NSPD, skipped in CI by default).
