Fixes getAlby/hub#76

@im-adithya are there supposed to be both permissions and scopes components? shouldn't you have renamed the permissions file to scopes so that there is a nice diff of the changes?

I think we should merge #508 first as we need to fix an issue with BTCPayServer and then fix the conflicts here.

[im-adithya]

Yeah, I will. I left this in between to prioritize the Send/Receive.

I was thinking of removing the use of Permissions component and doing a normal forEach listing of scopes in the ShowApp screen. So after this PR, the Scopes component would only be there to extract the scope group boxes (refer new design) and checkboxes out of the NewApp screen, and all the other permissions logic would be in NewApp itself

Closing in favor of #567
