fix(alarms): native-alarm re-statements no longer duplicate history or hide acked alarms (#656)

Browse Source 
- AlarmTransitionKind.ActiveAcknowledged (appended): active AND acked applied as ONE projection.
  Galaxy ActiveAcked snapshot entries and OpcUaClient inactive->(active,acked) use it; the
  projector writes 'Activated' only if not already active, 'Acknowledged' only if not acked.
- AlarmEventArgs.IsRestatement (optional, default false): set only by Galaxy snapshot entries
  and OpcUaClient first sight. A flagged Retrigger on an Active+unacked condition with the same
  message and severity, or a flagged Clear on an inactive condition, writes no /alerts row.
- NativeAlarmProjector reports the history rows per transition; ForwardNativeAlarm writes one
  row per entry. Unflagged sources (FOCAS/MTConnect/AbCip, live Galaxy) are unchanged.
- Tests: projector rules each with a must-write control; OpcUaClient transition table;
  Galaxy feed/driver mapping; Galaxy + OpcUaClient end-to-end through DriverHostActor.
