Ask with Unraid's own dialog, not the browser's

Every confirm() and prompt() in the plugin could be switched off from inside itself — one tick of
"prevent this page from creating additional dialogs" and all 32 of them returned false while
drawing nothing, across every tab, until a full reload. swal is already global on every webGUI
page and core uses it 370 times without a single confirm(), so this costs no new dependency.

vvConfirmRun() is the one that mattered: it returned a boolean to three callers testing !it, and
an unawaited promise is always truthy, so leaving those alone would have run every job without
asking. The wrapper's callback is a classic function expression on purpose — SweetAlert only
calls back on cancel when the callback's own source declares a parameter, and an arrow would
have hung the promise forever.
