fix: restore keyboard focus on action buttons after dismiss (v0.8.2)

After cancelling a confirmation prompt, the focused widget was removed
from the tree without restoring focus to the action buttons. With
layer-shell exclusive keyboard mode, GTK does not recover focus
automatically — the UI became keyboard-unreachable.
