Diagnostic + operator-facing documentation that closes the loop on the work in this PR.
`da diagnose` (via /api/health/detailed):
- New _check_bq_billing_project() helper. When data_source.type='bigquery' and BqProjects.billing == .data, surface a yellow warning: 'BigQuery billing project equals data project'. Hint includes the YAML field path + the /admin/server-config UI shortcut. Diagnose's overall status promotes warning → degraded so the CLI echoes it.
- Non-BQ instances (Keboola-only, etc.) skip the check.
- Implementation hooks into the existing /api/health/detailed surface — no new endpoint, no CLI changes.
config/instance.yaml.example documentation:
- data_source.bigquery.billing_project: USER_PROJECT_DENIED hint, /admin/server-config UI reference
- data_source.bigquery.legacy_wrap_views: analyst-side discipline note (use `da fetch` / `da query --remote`), issue #101 history, view-heavy deployment guidance
- data_source.bigquery.max_bytes_per_materialize: cost guardrail block (NEW — wasn't documented in .example before)
- ai.base_url: provider list + UI hint
- openmetadata + desktop: 'configurable via /admin/server-config UI' headers
- corporate_memory: leading note that the schema is editable via UI
