Block lists for riders and drivers #7

We need a function to block a driver, preferably in our ride history details for a given ride, and maybe later in the post-ride tip/rating screen when we make one. It could mute them using a Kind 30007 mute set. We need to make sure it doesn't overwrite the users mute set they already have one, if possible. Maybe it's possible later to bake in the # of mutes a person has against them into a rideshare reputation layer. Use the sync adapter skill to make sure this mute list syncs with backup and restore flow of nostr events.
