fix(ingest): wizard iceberg catalog key is uri, not catalog_uri

pyiceberg's load_catalog requires the key to be named uri; the worker
passes catalog_config to it verbatim, so every wizard-created iceberg
connection failed at catalog connection. The --config path was
unaffected (keys pass through as given). Test fixtures updated to use
the correct key so they stop enshrining the wrong name.
