Fixed useEffect dependency problem in SearchInput that caused
infinite re-renders when searching with 2+ characters.
Changes:
- Removed onSearch from useEffect dependencies
- Added ESLint disable comment for exhaustive-deps
- Search now only triggers on debouncedQuery changes
Issue: Search spinner would hang indefinitely when typing 2 chars
Root cause: onSearch callback recreated on every render, causing loop
Solution: Only depend on debouncedQuery in useEffect
