Move back link below search results on family tree search page

Repositioned the "← Back to Family Tree" link to appear below the search
results instead of above them. This improves UX by keeping the search results
more prominent and accessible, especially when there are multiple matches.

New layout order:
1. Search form
2. Results (when present)
3. Back to Family Tree link
