fix(widgets): display RuntimeError in widget output instead of swallowing

on_apply_button_clicked and on_down_button_clicked caught RuntimeError
with a bare `pass`, giving users no feedback when cluster operations
failed (e.g. K8s API unavailable, RBAC denial). Print the error message
to the widget output area so users can see what went wrong.

Fixes RHOAIENG-54733
