Add track coauthors with invitations, acceptance and coauthor-aware track responses

Owners invite existing users to coauthor a track; invitees accept or reject, and either side can remove a coauthor. Only accepted coauthors appear in track responses and in the coauthor's public track list. The owner also receives the full invitation list with statuses on the user tracks response.
