feat(recovery): improve ability to validate the address added as recovery

[zerosnacks]

When adding a recovery wallet on https://stg.id.porto.sh/ the following screen in shown:

It is already quite common for phishing campaigns to mine addresses matching 4 leading characters and 4 trailing characters as they know people briefly check the front and back.

Because the address shown is truncated I have no way to make sure this is actually my address.
I would like to be able to click on the address to see it in the explorer like is done here:

Additionally I think it would be good if the Recovery flow would ask me to sign a message on the wallet I am proposing to add as backup. This makes sure I actually own the recovery wallet.

In the Recovery section on https://stg.id.porto.sh/ I also would like to be able to see the full address, either on hover or include a link as is shown in the Permissions section.

The Public Key copy is also not entirely clear to me - is this an Ethereum address or the entire public key? If the latter - is this relevant to the user?
