Improve Fedora Podman compose compatibility

[SmartAI]

Summary

• use fully qualified Docker Hub image names in compose examples so Fedora/Podman deployments do not stop on short-name resolution prompts
• fix Redis compose startup commands so persistence/auth flags are passed to redis-server correctly
• document Fedora / Podman / SELinux notes for local-directory deployments
