fix(federation): auto-create and hydrate user profiles during DM relay

Federated 1-on-1 DMs showed the raw snowflake ID as the display name
and no avatar when the remote user had no pre-existing local record.
processCreateEvent used resolveLocalUser (find-only) instead of
resolveOrCreateReplicatedUser, and relay events carried no profile data
for participants.

- Add profile snapshot (displayName, avatar, avatarColor) to
  FederationRelayParticipant and populate it in getDmParticipants
- Change processCreateEvent to auto-create replicated user stubs and
  hydrate them with profile data from the relay event
- Fix hydrateReplicatedUserProfile URL resolution for homeInstance
  values without protocol prefix
- Fix WelcomeHeader: return null while DM data is loading (eliminates
  "unknown" flash on reload), use displayName for @mention text
