-- Per-card Jira sync state. Populated by the dispatcher after every push to
-- Jira so the frontend can render an indicator (gray/yellow/green) and a
-- tooltip with the last known status without polling Jira itself.
--
-- jira_last_status: the Jira status name the card was transitioned to in the
--                   most recent successful sync (e.g. "In Progress", "Done").
-- jira_last_sync_at: RFC3339 timestamp of the last sync attempt (success or
--                    failure).
-- jira_last_error: the error message from the last failed sync, or empty when
--                  the last sync succeeded.
