[Feature] Warn when I'm about to sign a kind 3 event containing less than 2 p-tags

[alexgleason]

Feature description

There is a problem pervasive in Nostr, due to the design of follow lists, that can cause users to inadvertently overwrite their entire follow list when signing into a new client.

Ideally this should be fixed by clients, and the protocol itself should be improved, but the signer can be another line of defense.

Describe the solution

Even if the user has authorized all events for a particular domain, Alby should still warn them if they're about to sign a follow list containing less than 2 p-tags.
