One prompt for the whole app, asked where the browser cannot refuse it

Fifteen destructive actions were still gated behind window.confirm(), the
same call that made removing a home charger look broken: a browser that
suppresses native dialogs never shows it and returns false, so deleting a
service, a part, a user or an organization would quietly not happen and say
nothing about why.

askConfirm() puts the question in the page and resolves to what was
actually pressed, so each call site changed by one line and reads the way
it did before. ConfirmDialog is mounted once in App.vue and draws over
everything, including a modal — removing a server is asked from inside one,
which is what Modal's new zIndex is for.

The home charger keeps its own inline prompt: that one belongs to its row
rather than to the middle of the screen.
