Add security classification, alarm detection, historical data access, and primitive grouping

Wire Galaxy security_classification to OPC UA AccessLevel (ReadOnly for SecuredWrite/VerifiedWrite/ViewOnly).
Use deployed package chain for attribute queries to exclude undeployed attributes.
Group primitive attributes under their parent variable node (merged Variable+Object).
Add is_historized and is_alarm detection via HistoryExtension/AlarmExtension primitives.
Implement OPC UA HistoryRead backed by Wonderware Historian Runtime database.
Implement AlarmConditionState nodes driven by InAlarm with condition refresh support.
Add historyread and alarms CLI commands for testing.
