Add user validation popup for adding Asset

[peterjah]

Context
Today, any dapp or software can add an asset in your massa wallet, just by calling an endpoint. It would make sense that user must confirm the add, to avoid spamming

todo:
Add a new wails workflow to confirm token addition. ( I think the password is not needed for this one)

Determine the flow here please @peterjah .
If I understand there are 2 ways of adding a token:
A) user manually via UI,
B) via API endpoint, a DApp can call it and add the token into user's assets, without user's permission (??)

If that's the case, we must create the confirmation only for B).

@peterjah I need more details on this

[peterjah]

there is only one way to add a token: calling the wallet api. the A) option is just a UI interface to do it. but it does option B) under the hood
