Allow to manage verifiable domains

[roman-khimov]

Is your feature request related to a problem? Please describe.

I'm always frustrated when we have some features that are not easily accessible. We've got cool verifiable domains, but managing them via CLI is not very user-friendly.

Describe the solution you'd like

Allow to manage them via Panel. There is a problem though, it's an FS chain operation and wallets are not likely to be aware of it.

Additional context

Just an idea for now.
