- Add defensive guards in EnvironmentContextWrapper to validate data before rendering
- Add loading.tsx for Next.js automatic loading state during navigation
- Handle AuthorizationError gracefully in layout to prevent crashes
- Fixes issue where environment becomes undefined during rapid page navigation
