Feature request: Ultrawide monitor support in Pokémon TCG Live

Hi Pokémon TCG Live team,

I'd like to suggest adding proper support for ultrawide monitors. When I play on an ultrawide display, there are large blank areas on both sides, leaving a lot of the available screen space unused.

Could you please add support for wider aspect ratios, such as 21:9 and 32:9, and allow the game layout and background to adapt to the full screen width? Ideally, this would make better use of the extra space while keeping cards and interface elements correctly proportioned, without stretching or cropping them.

This would make the game look and feel much better on ultrawide displays. Thank you for considering this suggestion!
