-- Snapshot the sender's languages on each feedback message, taken at submit time so the
-- operator console shows the state as it was, not the account's current settings (the same
-- snapshot discipline as a suspension's reason). lang is the sender's interface language;
-- channel_lang is the connector bot language (en/ru) when the message arrived through an
-- external connector (Telegram), else NULL. Additive over 00004 so it applies forward-safe.
