/**
* Migration from v4.0 to v4.1
*
* Major changes:
* 1. Moves thresholds from UPS level to action level
* 2. Creates default shutdown action for UPS devices that had thresholds
* 3. Adds empty actions array to UPS devices without actions
* 4. Adds empty actions array to groups
*
* Transforms v4.0 format (with UPS-level thresholds):
* {
* version: "4.0",
* upsDevices: [
* {
* id: "ups-1",
* name: "UPS 1",
* snmp: {...},
* thresholds: { battery: 60, runtime: 20 }, // UPS-level
* groups: []
* }
* ]
* }
*
* To v4.1 format (with action-level thresholds):
* {
* version: "4.1",
* upsDevices: [
* {
* id: "ups-1",
* name: "UPS 1",
* snmp: {...},
* groups: [],
* actions: [ // Thresholds moved here
* {
* type: "shutdown",
* thresholds: { battery: 60, runtime: 20 },
* triggerMode: "onlyThresholds",
* shutdownDelay: 5
* }
* ]
* }
* ]
* }
