fix things missed in the ingest migration

[damonmcc]

related to #1255 and a follow-up to recent PRs/ingest runs

Fixes the four product builds that nightly QA has been failing on since the mappluto and pops ingest migrations landed. Consumers were still reading wkb_geometry from datasets whose ingest archives now carry geom, so FacDB, KPDB and CPDB died in SQL and green_fast_track died on a source test.

• facdb _create_facdb_spatial.sql, kpdb combine.sql and dcp_housing.sql, cpdb stg__dcp_mappluto_wi.sql now read geom for dcp_mappluto_wi
• dcp_pops.yml no longer renames geom to wkb_geometry. That rename was mine and it was pointless: the only postgres consumer builds its own geometry from location/xcoordinate, while green_fast_track reads the parquet through duckdb and expects geom like every other parquet source. Re-archived at 20260713, same 38 columns and 392 rows, only the column name differs
• stg__pluto.sql casts spdist3 to varchar. Arrow nulls land as INTEGER in duckdb, so the LIKE against it failed there even though the same SQL is fine on postgres
• status csv regenerated: 246 rows, 183 archived via ingest, 0 flagged stale

Two unrelated fixes that were in the way:

• build commands now stream their output instead of buffering it. capture_output=True plus a single logger.info turned a whole dbt build into one log record, so CI showed nothing for five minutes and then a wall of text that the log viewer wrapped mid-word, with the formatter's color codes nested inside dbt's
• cpdb's projects_in_geographies builds one engine instead of 210. It was calling create_engine twice per geography and never disposing

Built all four on this branch: cpdb, facilities, knownprojects, green_fast_track. green_fast_track is PASS=313 WARN=6 ERROR=0 SKIP=0 across 319 nodes, the 6 warns being the stale equality fixtures already tracked in that product's issues.md.
