Latest update broke account managing (v0.7.0-4154) (Worked last update, I think) + 1 other bug

Description of bug

First thing I did after the update was clear all my accounts to start reading them since i didn't immediately see how to sign back into the Microsoft accounts linked to each account (I've been maining one to two accounts for a while but decided to finally fix the others). Then i started adding them one by one and noticed a few issues with the account manager as well as the new skin manager features.

Skin manager bugs:

• Skins uploaded as classic skins but used as slim skins display as all black in the new skin viewer
• Skins uploaded as classic skins but used as slim skins do not get saved when clicking "Save Skin To File"
• Skins that are classic skins cannot be used as slim skins (They should allow this as does Microsoft's skin "manager")

Steps to reproduce

Account manager bugs:

Take 1:
1 - Sign into account
2 - Sign into another account
3 - Launch random vanilla build (24w18a)
4 - Account needs to be manually signed into???

Take 2:
1 - Clear all accounts and sign into ONE account
2 - Launch random vanilla build (24w18a)
3 - It worked and let me into the game

Take 3:
1 - Clear all accounts and sign into ONE account
2 - Immediately refresh accounts
3 - It worked

Take 4:
1 - Repeat take 2
2 - Sign into second account
3 - Click refresh
4 - First account expired and second account Online???

Wanted to play MC a bit but looks like I'm gonna wait for the next release.

Edit: Forgot to do labels beyond "bug"

Not sure about the other issues you mention here. Looks more like Mojang/MS services being unreliable.

There are some things I can improve by preventing some of the token refreshes because we run into rate limits, but that's basically it...
