feat(search): implement paginated API fetching for large page sizes

- Removed upper limit on page_size validation to support requests >100
- Added automatic pagination logic to fetch from Open Food Facts API in chunks of 1000
- Accumulates products across multiple API pages until desired count is reached
- Updated error messages and product data fields for consistency
