fix: Avoid linebreak in balance label

[codesoap]

With my setup, there is a linebreak in the "Available Balance" label:

I think the "available" doesn't add any significant info, so I suggest just removing this "prefix".

What browser are you using ?
Is it the same for "Ready to receive" ?
edit: Just seen in your screenshot it's only for the balance...

I might look into adjusting the css instead of shortening the label

I'm using Firefox, but I think the important variable might be the different font on my OS. I think some margin for wider fonts should be included.
