pyproject.toml(chore[mypy]): Exclude frozen_dataclass_sealable test files from type checking

why: The frozen_dataclass_sealable decorator adds attributes and methods dynamically at runtime,
which mypy cannot properly analyze in test contexts, resulting in false positive errors.

what:
- Added mypy override to ignore type errors in tests._internal.test_frozen_dataclass_sealable
- Added mypy override to ignore type errors in tests.examples._internal.frozen_dataclass_sealable.test_basic
- Preserves strict typing for the implementation code while allowing tests to use dynamic features

refs: This addresses the mypy test failures while maintaining type safety for the implementation
