feat(tradein): postgres_fdw live read of gendesign.cad_buildings (replaces snapshot)
Replaces tradein.cad_buildings manual snapshot (36k rows, frozen 2026-05-22) with
live postgres_fdw foreign table reading gendesign.v_tradein_cad_buildings directly.
Also reverts PR #492 HTTP-based cadastral.py — superseded by FDW.
Architecture:
- gendesign DB: new role tradein_fdw_reader + flat view v_tradein_cad_buildings
(EKB-only slice of cad_buildings with lat/lon flattened from geom)
- networks: gendesign-postgres added to gendesign_shared (alias);
tradein-postgres added to gendesign_shared for FDW connect
- tradein DB: postgres_fdw extension + FOREIGN TABLE gendesign_cad_buildings
- tradein backend: startup hook creates/refreshes USER MAPPING with password
from env GENDESIGN_FDW_PASSWORD (password rotation handled via restart)
- geocoder.py: cadastral primary for forward + reverse + suggest;
Yandex/Nominatim fallback. reverse_geocode wraps Nominatim in try/except —
no more HTTPStatusError → 500.
- house_metadata.py and trade_in.py admin stats switched to foreign table
- DROP TABLE cad_buildings in tradein (legacy snapshot removed entirely)
- import-cadastre.sh deleted (no manual sync needed)
Fixes:
- /trade-in/api/v1/geocode/reverse 500 (Nominatim ban → no fallback)
- estimate confidence_explanation=address_not_geocoded for addresses in our
cadastre (e.g. Хохрякова 81) that Nominatim doesn't return
Deploy ordering: main migration 100_tradein_fdw_role.sql adds role+view first
(strict deploy.yml). Tradein next deploy applies 060_postgres_fdw_extension.sql
and 061_drop_legacy_cad_buildings.sql (idempotent, errors ignored). Tradein
backend startup creates USER MAPPING when env var present. Verify post-deploy
with: docker exec tradein-postgres psql -U tradein -d tradein -c \
"SELECT count(*) FROM gendesign_cad_buildings" # expect ~36k EKB buildings.
