let hosts override the interactive auth banner

[danielroe]

Clear and concise description of the problem

we're working on an interactive terminal UI for nuxt cli, and part of this is being able to embed elements like notifications, prompts, and so on (see nuxt/cli#1488)...

for DevTools, the OTP banner is the one bit of output we cannot easily re-skin.

Suggested solution

we do have somewhere it could live (a sticky notice on the dev panel that dismisses on keypress), but we can't get the code out of devtools

createInteractiveAuth takes banner?: (info: { code, url }) => void, but it isn't currently threaded through.

we could do something like this:

// vite.config.ts, or from a framework integration
devtools: {
  banner: ({ code, url }) => myTui.notify(`DevTools auth code ${code} (or open ${url})`),
}

it would fall back to the current default when it's unset, so nothing would change for plain vite dev.
