fix(workflows): guard list against corrupted registry entries, re-raise typer.Exit in catalog install

workflow list now skips non-dict registry entries with a warning instead
of crashing, matching update/enable/disable. The broad except in
_install_workflow_from_catalog no longer swallows typer.Exit, so precise
errors like the non-HTTPS redirect message are not duplicated.
