Spec for the upcoming fix: when query_mode='remote' BigQuery rows have a
VIEW or MATERIALIZED_VIEW entity, da query --remote currently fails with
DuckDB catalog error because the extractor (with legacy_wrap_views=False
default) skips master view creation for those entity types.
Plan:
- always create master view (Storage Read API for BASE TABLE; jobs API
via bigquery_query() for VIEW/MATERIALIZED_VIEW); remove the
legacy_wrap_views config knob entirely
- add server-side cost guardrail on /api/query (5 GiB default cap,
per-user daily-byte + concurrent-slot quota shared with /api/v2/scan)
- close pre-existing RBAC hole on direct bq."ds"."tbl" references
(registry-gated; admin must register first)
- add bigquery_query() to SQL blocklist (closes function-call backdoor)
- shared CLI structured-error renderer (cli/error_render.py) so typed
BqAccessError details render readably instead of raw JSON dumps
- /admin/server-config: BQ "Test connection" button + placeholder for
billing_project showing the resolved fallback to data project
