no-bug: add a "100%" size override value in boosts

[ashvwinn]

Adds a new "100%" size override value in boosts. I think a lot of people has their default zoom set to something else other than "100%", so they might need it sometimes.

This is how the colos look:

Light mode

Dark mode

Should I add the contrast change in this PR? Its a small change so idk

Not too sure about this tbh, this would just add more complication, looks more like a workaround rather than fixing the actual issue. That, without saying that 100% is the default zoom anyways

I know it's not a fix which is why I closed the last PR and didn't link the issue here either, but I still think adding a 100% size option is good.
I myself use 110% as the default size so if I want to set the size as 100% with boosts, I just can't without the option.
