GuildFriendListTask.Parse() reads base.ResponseData[data][i] directly —
data must be a bare JSON array, not {friends:[...]}. Delete the
GuildFriendListResponse wrapper DTO; promote GuildInviteCandidateDto to its
own file. Controller now returns List<GuildInviteCandidateDto> so the
middleware wraps it as data:[…]. Update wire-shape and integration tests to
assert array-at-root.
