update header ads (#2266)

## Description:

1. Remove SpawnAds and replace it with AdTimer which will delete the
in-game ad after the first minute.
2. remove login blocker UI, we don't use it anymore
3. convert TerritoryPatternsModal & GutterAds to use event based when
checking for flares
4. remove window.PageOS.session.newPageView(); because it was throwing
an exception
5. Convert SpawnTimer to a lit element to give it a higher z-index to
stay above the header ad

## Please complete the following:

- [x] I have added screenshots for all UI updates
- [x] I process any text displayed to the user through translateText()
and I've added it to the en.json file
- [x] I have added relevant tests to the test directory
- [x] I confirm I have thoroughly tested these changes and take full
responsibility for any bugs introduced

## Please put your Discord username so you can be contacted if a bug or
