List user trophies

Returns every trophy awarded to the user, sorted newest first by awardedAt, as an unpaginated list with a count (no cursor or limit). The identifier is a username or Convex user ID. Visible only when the target profile is effectively public, or when the profile belongs to the API key owner (self-view is always treated as public); a non-self limited or private profile returns 403. An unknown or banned user returns 404. Event linkage fields such as matchId and tournamentId are omitted. Requires users.profile:read.
