Show and extend the elevation window

A banner appears while elevated, counting down in minutes and carrying
extend and drop controls. Three extensions of 30 minutes are allowed, so
the window is at most two hours without a fresh code; a code resets the
budget. The countdown is advisory, the server-side check authoritative, so
it says "expired" rather than vanishing.

The post-login flash tells an admin the timer has started.
