fix: add DB wait-for-ready logic and explicit network names

- start-with-migrate.js now waits for the database TCP port to be
  reachable before running Prisma migrations (15 retries, 2s interval).
  Prevents the container from crashing and restarting in a loop when
  postgres is still starting up.
- Add explicit 'name:' to both production and dev compose networks
  to prevent docker-compose project prefix mismatch.
