SocialMedia.Channels returned the stored channel entity from GetChannels and
AddChannel, so every connected account's AccessToken and RefreshToken were serialised

"name||RAW:key". Only the hash was ever persisted, but the shape was one accidental
re-save away from writing a live key into the database in plain text. It now returns a
dedicated result, shown once.

nothing.
