Add fixed UUIDs to all development seeders for programmatic API access:
- Server: localhost
- Project: project
- Applications: docker-compose, nodejs, dockerfile, dockerfile-pure
- StandaloneDocker: docker
- StandalonePostgresql: postgresql
- S3Storage: minio
- PrivateKeys: ssh, github-key
- GithubApps: github-public, github-app
- GitlabApp: gitlab-public
- LocalPersistentVolume: volume
