Prisma 7 breaking changes to Prisma config file, and prisma schema
Fixes Prisma 7 breaking changes: the P1012 error 'The datasource property url is no longer supported in schema files' and seed failures, by moving config to prisma.config.ts with an explicit adapter. Use when upgrading to Prisma 7 breaks prisma generate, migrate deploy, or seeding. Not for Prisma 5/6 config issues.
