Fix remaining test failures after removing mocks

- Fixed LangGraphAdapter test to use model registry from fixture
- Fixed web tools test to use default config instead of missing file
- Removed problematic model registry debug test
- All tests now use real models and no mocks

This completes the work on issue #93 to remove all unittest.mock usage
and ensure tests use real implementations.
