Fix final Supabase build error in admin-auth and backup

- Fix lib/auth/admin-auth.ts: Convert module-level Supabase client to lazy initialization
- Fix lib/database/backup-strategy.ts: Convert backupManager to createBackupManager function
- Fix app/api/admin/backup/route.ts: Update to use createBackupManager function
- This resolves the final 'supabaseUrl is required' build error
- Build now completes successfully with all 142 pages generated
