Fix(docker): optimize pnpm build and explicitly set image tag

- Update Dockerfile:
  - Add `package-import-method copy` to pnpm config to resolve EAGAIN errors during build.
  - Optimize pnpm network concurrency settings.
- Update docker-compose.yml:
  - Explicitly set `image: hotwa/bttoxin-app:latest` for services.
