FRP: Add to wallet toast

[Majorfi]

What is your proposal 🚀

Add a toast to add the TO token to wallet once a swap is performed (while waiting for it to be mined).
The toast should not disapear unless explicitly closed or if another transaction is initialized.
Design available on Figma

What does this solve ? 🛠

Can be hard to track the token to your wallet and the "mini wallet view" is almost hidden so no easy access to that
