fix(docker): generate Prisma client before turbo build

Prisma generate was running AFTER pnpm turbo run build, causing TypeScript
to compile the API without the generated Prisma types. This made all Prisma
query result types resolve to 'any', triggering TS7006 on every callback
parameter (.map, .filter, .reduce) in strict mode.

Fix: move prisma generate to before turbo build in the builder stage.
