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.

GuildUpdateTask.Parse() reads data[guild] as GuildDetailInfo directly; the previous
GuildDetailSubTree wrapper (data[guild][detail]) caused json[guild_id].ToInt() to
crash on the client. Split GuildUpdateResponse (flat) from GuildUpdateEmblemResponse
(nested, correct for GuildEmblemUpdateTask.Parse). Also surfaces guild_name from the
request through UpdateGuildRequest.Name -> service -> repo so the client rename is honoured.
