Add: tmpfs and volume prune and kadmin_api depends on kdc

[milov-dmitriy]

• tmpfs: чтобы не хранить данные после запуска тестов
• volume prune: чтобы очищать volume от неименованных контейнеров
• kadmin_api depends on kdc: оба этих контейнера создают одну папку, из-за чего возникал race_condition, теперь нет

Pull request overview

This PR addresses three infrastructure improvements for Docker Compose configurations: fixing a race condition between Kerberos services, preventing test data persistence, and automating volume cleanup.

Changes:

• Added dependency for kadmin_api on kdc service to resolve race condition on shared volume creation
• Added tmpfs mounts for PostgreSQL and Dragonfly test databases to store data in memory
• Added automatic unnamed volume cleanup to the down make target
