Fix Device UUID alignment between ConfigDB and Sparkplug Instance_UUID

[AlexGodbehere]

Summary

• Helm pre-upgrade backup hook: runs pg_dump of the ConfigDB before every helm upgrade, stores timestamped backups in a PVC, keeps last 5. Aborts the upgrade if the backup fails. Configurable via configdb.backup.* in values.yaml (default: enabled, 2Gi storage).
• ConfigDB v13 migration: aligns existing Sparkplug Device object UUIDs with their Instance_UUID from the origin map. Includes a pre-flight check for duplicate Instance_UUIDs that fails cleanly and allows retry after fixing. Also wires in the previously un-wired v12 migration.
• Admin UI fix: prepareModelForSaving() in OriginMapEditor.vue now uses the device's ConfigDB object UUID as the top-level Instance_UUID instead of generating a random UUID. This prevents Instance_UUID regeneration on schema change and ensures new devices are aligned from creation.

Test Plan

• Run helm template and verify pre-upgrade-backup Job and PVC render correctly
• Build dev release and install on development cluster
• Deploy to a test cluster, run helm upgrade, verify a backup appears in the configdb-backups PVC
• Verify a second upgrade rotates backups correctly (keeps last 5)
• Create a new device in the admin UI, save the origin map, verify Instance_UUID in ConfigDB config matches the device's object UUID
• Change a device schema, reconfigure, save — verify Instance_UUID is unchanged
• On a test cluster with existing devices, verify the v13 migration runs and aligns device UUIDs without data loss

Notes

Although the upgrade seemed to change the UUID I'm getting intermittent connectivity issues with Grafana and devices dropping. Need to investigate logs on fpd-ago.

@amrc-benmorrow FYI.

Update:
Restarting all services (including edge services) seemed to solve this.

LGTM assuming it tests OK
