Added better UX and debugging for the comparison screen:
1. Loading state for chart section
- Shows "Loading comparison data..." when schools are selected
but data hasn't loaded yet
- Provides visual feedback to users
2. Enhanced debugging logs
- Log URNs being fetched
- Log API response status
- Log received comparison data
- Better error handling with null state on failure
3. Improved conditional rendering
- Chart shows when data is available
- Loading message shows when waiting for data
- Nothing shows when no schools selected
This helps diagnose any API issues and provides better user feedback
during data loading.
