RTL languages

[tttp]

we have already Arabic and Hebrew in weblate, but we need to check how to have RTL widgets

mui has an parameter for that

@1v4n4 could you check (hard coded) see how it works and if it does, add a new config layout: right2left = true or whatever is matching the mui naming

Here's what needs to be done for RTL to work https://mui.com/material-ui/guides/right-to-left/. I'll try to implement it

Checkboxes also look weird



Nonecis

But it is not bad for 10 lines of code...
