The compare screen and school search modal were not working because
they were fetching from '/api' directly instead of using the
NEXT_PUBLIC_API_URL environment variable that points to the backend.
Fixed client-side fetch calls in:
- ComparisonView: Fetch comparison data with correct API URL
- SchoolSearchModal: Search schools with correct API URL
This ensures client-side requests go to the FastAPI backend at
the configured URL (e.g., http://localhost:8000/api) rather than
trying to hit non-existent Next.js API routes.
Fixes comparison screen showing no data when schools are selected.
