Add Public Key to Account Details

**What problem are you trying to solve?**
Be able to easily see the pubkey for an account.

**Describe the solution you'd like**
When clicking on Account Details, there could be another section Advanced. When Advanced is clicked, it would show other advanced information about the account, such as the Public Key.
Maybe this logic can be run on demand, when the Advanced option is selected: this way, it does not need to be computed for all accounts.

Start by finding the Account Details view and tracing the account data it exposes. Confirm how an Advanced section should present the public key and whether its computation can be deferred until the section is opened; done means the public key is visible there without being computed for every account.
