fix: Implementasi retry mechanism dan error handling untuk database connections

Deskripsi:

Menambahkan withRetry wrapper pada berbagai API routes untuk menangani transient database errors dan meningkatkan reliabilitas koneksi

Memperbaiki error handling pada notification, authentication, dan user validation endpoints dengan response 503 untuk database connection errors

Update prisma.ts dengan konfigurasi logging yang lebih baik dan datasources configuration

Menambahkan validasi input parameters pada beberapa endpoints

Update dokumentasi QWEN.md dengan commit message format dan comment standards

Update .env.example dengan connection pool settings yang lebih lengkap

File yang diubah:

src/lib/prisma.ts — Konfigurasi Prisma client & logging

src/app/api/admin/notifikasi/count/route.tsx

src/app/api/auth/mobile-login/route.ts

src/app/api/mobile/notification/[id]/route.ts

src/app/api/user-validate/route.ts

Dan 27 file API routes lainnya (penerapan withRetry secara konsisten)

QWEN.md — Dokumentasi commit & comment standards

.env.example — Database connection pool configuration
