fix: prisma connection exhaustion & firebase lazy init
- prisma/schema.prisma: tambah binaryTargets debian & linux-musl untuk Docker - src/lib/prisma.ts: pakai global singleton di dev & prod, hapus eager $connect() - src/lib/firebase-admin.ts: lazy initialization agar tidak crash saat build time - .env.example: lengkap dengan semua env variable + connection_limit & pool_timeout Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
