No, that's a propre solution.

I wouldn't set it to trigger every second. This causes an unnecessary
high load on the server. A value that is just a bit shorter than the
expiry time is fine.

Sure, using JavaScript. You take one of the many countdown scripts
from the web, add and initialize it with the session expiry time
whenever you render a page.
