E2E Test Plan

Setup:
- Log in with a user that has appropriate permissions
- Navigate to /policy
- Ensure test data exists (scanned artifacts, SBOM data, or seed data as needed)
Core verification:
- Verify the component renders correctly with sample data
- Verify interactive elements respond to user input
- Verify data is fetched and displayed from the correct API endpoints
Edge cases:
- Verify graceful handling when backend API is unavailable (error state)
- Verify responsive layout at different viewport sizes
- Verify accessibility (keyboard navigation, screen reader labels, ARIA attributes)
