fix: revert enable_realtime SQL wiring until constructive-db#1105 is merged

The CI database doesn't have the enable_realtime column yet, so the
COALESCE query fails. Keep the hardcoded enableRealtime: false for now;
the SQL wiring will be a follow-up commit once the DB migration lands.

The log.warn fixes for silent catch blocks are retained.
