**Additional context**
After updating podman from 5.5.0 to 5.5.1

Start by tracing the Toolbx Podman migration path that runs during `toolbox enter`, focusing on the `podman system migrate` invocation and the remote-client error. Reproduce with Podman 5.5.0 to 5.5.1 on Fedora Silverblue 42; done means entering the container succeeds without the migration error.
