-- Extend issue.origin_type to allow the Lark `/issue` command path to stamp
-- issues with origin_type='lark_chat' + origin_id=<chat_session.id>. Without
-- this entry in the CHECK list, every /issue dispatch on Lark fails with
-- SQLSTATE 23514 and the connector exits with infra error — see Bohan's
-- live-env repro in MUL-2671 review where one /issue in a row tripped the
-- check three times, each crash dragging the WS connector down + Lark
-- retrying the same event into the next crash.
