Summary

Restores url = env("DATABASE_URL") to the datasource db block in prisma/schema.prisma
Fixes PrismaClientConstructorValidationError crashing next-auth's OAuth callback handler

Root Cause

In Prisma 7, prisma.config.ts only configures the CLI (migrations, db push, etc.) — it is not read by the runtime PrismaClient. With no url in the datasource block, the generated client defaulted to engineType = "client" (WASM), which requires either a database adapter or Prisma Accelerate URL to be passed to the constructor. Since neither was provided, every database call threw a PrismaClientConstructorValidationError, which surfaced as a next-auth adapter_error_getUserByAccount on OAuth callback.

Test plan

Rebuild Docker image and verify OAuth login completes without adapter_error_getUserByAccount
Confirm DATABASE_URL=file:/app/data/dev.db is set in the container environment

fix: restore DATABASE_URL in schema.prisma for Prisma 7 runtime client 042c45d9dd

Prisma 7's prisma.config.ts only configures the CLI, not the runtime
PrismaClient. Without url in the datasource block, the generated client
defaults to engineType "client" (WASM) which requires an adapter,
causing next-auth adapter errors on OAuth callback.
