Answer 1

Out of loyalty to users, I won’t specifically tell you how to do this.
I hate those stupid modals.

Answer 2

setInterval(function  () {
  // body...
}, 180000) // 30 минут

Answer 3

Since the site is not a SPA, the method with setTimeout will not help, it is necessary to write the current time on the first page load (timeFromCookie = Date.now() - for example), in the cookie or localStorage - in order to then take this time and compare it with the current one, and watch how long has passed: (Date.now()- timeFromCookie) / (1000 * 60 * 30) > 1 - if the expression is true, then more than half an hour has passed. To compare, you can write a function using setInterval, which, say, once a minute will check the current time and the time from the storage. And run it immediately when the page loads.

Answer 4

You have a good site, since users sit on it for an hour
