Joseph Doherty 205b07f6aa fix(driver-historian-wonderware): resolve Medium code-review finding (Driver.Historian.Wonderware-002)
Normalise req.Events to Array.Empty<AlarmHistorianEventDto>() immediately
after MessagePack deserialization in HandleWriteAlarmEventsAsync. MessagePack
deserializes an absent or explicit-nil array field as null, not Array.Empty,
so a peer that sends a null Events array would trigger a NullReferenceException
on either .Length dereference (no-writer branch or catch block), leaving the
client correlation-id wait hanging with no reply frame.
