Adds src/helper/formatters/frostFormatter.js — structured-envelope formatter parallel to the InfluxDB one. Produces dbase messages that a CoreSync collector can forward to FROST/SensorThings without coupling producing nodes to FROST HTTP details. Registered in formatters/index.js.
Config additions in 4 node schemas (machineGroupControl, measurement, pumpingStation, rotatingMachine) expose the new dbase format option in the editor.
Part of the CoreSync FROST handoff initiative — see superproject CORESYNC_FROST_INTERVIEW_HANDOFF.md.
