feat: Implement Load More pagination for matches page

- Add pagination state management (matches, hasMore, nextPageTime)
- Create loadMore() function to fetch and append next page of results
- Replace placeholder "pagination coming soon" with functional Load More button
- Add loading spinner during pagination requests
- Show total matches count and "all loaded" message when complete
- Use $effect to reset pagination state when filters change

Completes Phase 5.2 pagination requirement from TODO.md.
Users can now browse through large match lists efficiently.
