Add the words "Wallet Address" above the wallet address on the Tokens screen

[waveform06]

Describe the bug
Lots of people say they have trouble finding the wallet address or are unable to copy the address from somewhere in the app. And never notice that its right there in front of them above the wallet value in the Tokens screen, with a copy icon.

To Reproduce
Just goto the ($) tokens tab

Expected behavior
Add some text describing that the Wallet Address is the text below
Maybe also put an extra blank line between the wallet address and the wallet value to separate them
