fix(console): use toast for pip-install error display (#8462)

* fix(console): use toast for pip-install error display

The pip-install dialog displayed error messages as unstyled inline
<small> text with no color differentiation from success messages.
Replaced with useToast() to show errors as red snackbar, consistent
with the rest of the dashboard.

* fix(console): use i18n for pip-install toast fallback messages
