fix: suppress AsyncMock RuntimeWarnings in Python 3.13+

In Python 3.13+, MagicMock auto-detects async-like method names (commit,
debug, warning, etc.) and returns AsyncMock objects. This causes
RuntimeWarnings when these methods are called synchronously.

This commit adds:
- A warning filter to suppress "coroutine was never awaited" warnings
- A setup_mock_g() helper for tests that need explicit MagicMock setup
- Updated create_mock_db_query() to also set up g.log
