fix(social): friend_request_sent local broadcast must carry target profile

The local branch was reusing friendRequestPayload (built for
friend_request_received with user=sender) for the sender-side
friend_request_sent broadcast. Tab B on the sender would render
the sender's own avatar where the target's should appear.
Match the federated branch — sent broadcast carries target.
