test(superset): add SQL Lab API and executor integration tests

- test_superset_sqllab_api_integration.py (8 tests): raw REST API with form-based
  auth — login via /login/, CSRF token, /api/v1/database/ listing,
  /api/v1/sqllab/execute/ (returns structured error without configured DB),
  400 on missing database_id, CSRF protection, 404 for non-existent DB,
  JWT failure documented per ADR-0012

- test_superset_sqllab_executor_integration.py (9 tests): httpx.AsyncClient
  with form-based auth — DB listing, SQL Lab, database by ID,
  SupersetSqlLabExecutor constructor + resolve_database_id,
  SupersetClient with container URL, batch_insert module import,
  raw API column listing

Total integration test suite: 25 tests across 3 files
(conftest: 6 fixtures — superset_container, superset_url, superset_admin_headers)
