Greptile Summary

Added optional chaining to handle undefined storyId values in the TestProviderRender component, preventing "cannot read property of undefined" errors when filtering test results.

• Added optional chaining in code/addons/test/src/components/TestProviderRender.tsx for result.storyId?.startsWith() checks
• Improved null safety when filtering test results for both component and accessibility tests
• Standardized handling of undefined values across status mapping and result sorting
• Ensured consistent error handling between a11y and component test result processing
