feat(native-alarms): per-binding IsMesReportable on native alarm source bindings (ScadaBridge#59)

TemplateNativeAlarmSource.IsMesReportable + tri-state InstanceNativeAlarmSourceOverride
.IsMesReportableOverride flatten onto ResolvedNativeAlarmSource; NativeAlarmActor stamps every
mirrored condition and InstanceActor the quiet-binding placeholder, so ScriptAlarm,
Alarms.MesReportableAsync() and the #60 wire fields carry it. Additive to the 900-999 severity band.
Migration AddNativeAlarmSourceMesReportable. Management commands, CLI --mes-reportable, Central UI
(template dialog checkbox, instance override select), Transport DTOs/importer/diff and the revision
hash (true-only, so existing hashes are unchanged) carry it.
