feat: migrate docker-compose to be compatible with rootless podman compose

[credfeto]

Problem

This repository uses docker-compose which requires a Docker daemon (typically run as root). We are migrating the infrastructure to use rootless Podman, which runs containers as an unprivileged user for improved security.

Required changes

• Replace any docker-compose files with podman compose-compatible equivalents
• Ensure no configuration relies on Docker-specific features that are absent in rootless Podman
• Test that podman compose up works correctly with the existing compose file(s)

References

• Podman Compose
• Rootless containers
