Fix Prisma

1 fix: error koneksi Prisma dengan retry mechanism
      2
      3 Perubahan:
      4 - src/lib/prisma.ts: Tambah retry (3x) dengan exponential backoff saat connect
      5 - src/lib/prisma-retry.ts: NEW - Utility wrapper untuk retry operations
      6 - src/app/api/user-validate/route.ts: Improve error logging dengan detail
      7 - src/middleware.tsx: Clean up commented code
      8
      9 Fitur:
     10 - Auto retry saat database connection gagal
     11 - Explicit () di production
     12 - Better error logging untuk debugging
     13 - Reusable retry wrapper (withRetry, withTimeout)
     14
     15 Testing:
     16 - Build berhasil ✅
     17 - Type checking passed ✅
