Fix final Supabase build errors in certificates routes

- Fix app/api/admin/certificates/participants/route.ts: Convert module-level Supabase client to lazy initialization
- Fix app/api/admin/certificates/data/route.ts: Convert module-level Supabase client to lazy initialization
- This resolves the final 'supabaseUrl is required' build errors
- Build now completes successfully with all 142 pages generated
- All Supabase build errors are now completely resolved
