Fix: Use centralized API functions instead of manual URL construction

- ComparisonView now uses fetchComparison from lib/api
- SchoolSearchModal now uses fetchSchools from lib/api
- Fixed bug in fetcher function that incorrectly sliced URLs
  (url.slice(4) was removing '/com' from '/compare')

This fixes the malformed URL issue where '/api/compare' became '/apipare'.
