Subject: [PATCH] feat(shared): types for federation user lookup + WS events

Add FederationUserLookupRequest, FederationUserLookupProfile, and
FederationUserLookupResponse for the peer lookup endpoint contract.
Add friend_request_sent and friend_request_relay_failed ServerEvent
variants alongside existing friend_request_* cases.
