fix: exclude prisma.config.ts from TS compilation, use datasource.url

prisma.config.ts is a Prisma CLI config file, not part of the Next.js
app — exclude it from tsconfig to prevent type errors. Also revert the
migrate.adapter block (not a valid PrismaConfig key in 7.5) back to
datasource.url which is the correct CLI config for db push.
