fix: Move testlinks page to API route to resolve static generation error

- Moved /app/testlinks/page.tsx to /app/api/testlinks/route.ts
- Fixed TypeScript null safety issue in regex match
- Removed empty testlinks directory

This resolves the 'Unsupported Server Component type: Module' error during build.
