Create read-only view mode

[LuizAsFight]

Right now we only allow to add accounts using 2 ways:
1- import from private key
2- add a derived account

Feature

This issue aims to add a new way of adding an account: "Add read-only account".

It can be another button in the same screen, but when you open it, instead of asking for a private key, it will ask for the public address.

This address will be added to the accounts list

Requirements

This new address added is one account of type "read-only", which means its only purpose is to see the public information this address has, but it won't be possible to execute any action that requires an unlocked wallet, since we don't have the private key, we only have the public key

Things like "Send Transaction" and any other action that is not read-only, should be disabled when accessing an read-only account
