Replace all `podman` CLI shell-outs with HTTP requests to the rootless
Podman API unix socket (/run/user/{UID}/podman/podman.sock).
Benefits:
- No process spawning overhead — direct HTTP over unix socket
- Structured JSON responses — no string parsing fragility
- Proper timeouts on all operations (5s connect, 30s default, 120s create)
- Health check method to verify socket availability
- Restart container as first-class operation
Still uses CLI for:
- Image pulls (streaming operation better suited to CLI)
- Container logs (raw text stream, not JSON)
The Podman socket is rootless (runs as archipelago user), local-only
(unix socket), and already behind our session auth in the backend.
