Modal to choose Langage on "splashscreen" can be wider than the visible window and overlaps other modals

[vericors]

Describe the bug
Open in the Language Menu on a vertical screen brings the modal out of bounds. To close it the user has to scroll to the right to find the "X". Scrolling to the right reveals the game (level) underneath.
The language Modal does not close the "settings" and "loadout" modal.

To Reproduce
Steps to reproduce the behavior:

1. Go to 'Splashscreen' suroi.io ;-)
2. Set the browser to simulate a mobile device e.g. iPhone 12 (Important in Portaitmode)
3. Click on the "Settings" button
4. Click on 'Language" button (Earth-icon bottom right)
5. (The settings are still open underneath)
6. Try to close the language modal. -> Scroll to the right. You'll see the level 'underneath'.

Expected behavior
Adapt the with of the modal to the size of the screen. Like with the settings and loadout modal. Close other modals when language moal is opened.
