Bug ticket: YQ-4778

Pull Request Overview

This PR fixes a bug where streaming query creation would fail when combined with other DDL operations like CREATE SECRET or GRANT statements. The fix involves updating the intent determination transformer to properly handle these operations instead of throwing errors.

Key changes:

• Modified the intent determination transformer to handle DDL operations alongside streaming queries
• Updated test fixture to use proper authentication setup for multi-operation scenarios
• Added comprehensive test coverage for streaming queries with mixed DDL operations
