Move player info panel to top of the screen & simplify (#3087)

related to #2260

## Description:

* Moves the player info panel from the right to the top of the screen
* Disable the header ad for now because it would cover up the player
info, we'll find a better place for it in the future
* Remove the collapsable button/functionality. It's hard to even click
the button because the panel disappears when you move away from a
player, and I think the info is too valuable to ever need to be
collapsed.
* Removed the "land" and "irradiated land" since it didn't add much
value
* Remove all alt text & translation, you can't hover over the player
overlay so it's irrelevant.
* put troop info inside the troop bar to reduce amount of text
