Add live e2e tests for the nostr relay and NIP-05 server

tests/nostr_e2e.rs (run with --ignored):
- nip17_slatepack_roundtrip: Alice gift-wraps a slatepack payment DM with a
  subject to Bob over wss://nrelay.us-ea.st; Bob unwraps, the seal-author ==
  sender invariant holds, the slatepack and subject extract intact.
- nip05_registration_roundtrip: registers a fresh name on goblin.st with a
  real NIP-98 signature, resolves it back to the right pubkey, releases it.

Both pass against the live deployed infrastructure.
