Minor UI issues on ultrawide aspect ratios

[JackDotJS]

Description

TF2's support for ultrawide displays is pretty decent. Most UIs work perfectly fine at basically any resolution, but there are at least two menus in particular that have noticeable (but minor) scaling issues, that being the team and class selection screens. Additionally, some UIs with image backgrounds (such as the main menu) don't seem to resize uniformly, resulting in very noticeable stretching on uncommon aspect ratios.

I'm not sure if this really qualifies for a bug report, but "feature request" didn't feel very fitting either. Sorry if this is wrong.

Reproduction

1. Use an ultrawide display, or set TF2 to use an ultrawide resolution via launch options (-w 3440 -h 1440 in my case)
2. Join any TF2 server, dedicated or otherwise (also applies to matchmaking)
3. Continue past MOTD/"Welcome" screen
4. See part of spectator UI in the background on the sides of the screen
