Convert blender tests to pytest with unified infrastructure

- Migrate 8 unittest-based files to pytest framework
- Standardize all test classes with unified mixins
- Implement BlenderTestMixin and TestAssertionsMixin in conftest.py
- Convert 4 test classes, 11 test paths, 33 test methods, 104 total tests
- Replace unittest imports and decorators with pytest equivalents
- Establish consistent mixin-based inheritance patterns
- Maintain all existing functionality while modernizing architecture
- Resolve complex inheritance chains like TestGenericJoinBefore
- Preserve parametrized test support throughout conversion"
