test(#551): pin browse-commit parity for MTConnect + MQTT, and record the Sql row-selector gap

Verified against the live mapper: every browsable driver's browse-committed
TagConfig passes the gate the commit now runs, EXCEPT Sql — its branch emits a
WideRow blob with no rowSelector, which SqlTagConfigModel and
SqlEquipmentTagParser both refuse. That tag was never readable; the gate only
moves the failure from the deploy gate to the commit. Reported for its own fix
rather than special-cased here.
