Feature: Nostr connect

[Fonta1n3]

Now that the app has been wiped of excess complexity we can add a cleaner flow for connecting to a node via nostr.

Pros:

• Speed
• Agnostic encrypted messages without node credentials.

Cons:

• Privacy, if a user is not utilizing Tor or a VPN your IP will be leaked, since the comms are agnostic and encrypted with a user provided key it should not be too much of an issue?
• Getting rate limited by public relays, user should run something like nostrnode alongside their node, will be adding this to Fully Noded Server. Perhaps we batch rpc commands to avoid getting rate limited by public relays?
