NIP-05 verification for pubkeys in message modal

[bnonni]

Message modal displays raw pubkeys. It would be better to show the NIP-05 verified username instead (if present), and then link to it.

• intermediately, get npub rendering and linked instead of raw pubkey
  then ...
• use pubkeys object to get a list of pubkeys
• query relay for events kind 0 passing pubkey as author
• do 1 of 2 things:
  • store all metadata objects in Map(<pk>: {metadata}, ...) for easy querying in augUIModal fn
  • query relay in the augUIModal fn in real-time to get nip05
