fix(transport): transport template NativeAlarmSources — imports no longer amputate native alarm mirrors nor dangle instance overrides

New TemplateNativeAlarmSourceDto + init-only TemplateDto.NativeAlarmSources (empty default, additive — IsInherited placeholders carried for the collision detector). Exported in ToBundleContent, consumed in FromBundleContent + BuildTemplate, and a new SyncTemplateNativeAlarmSourcesAsync runs the Overwrite add/update/delete child sync with per-change audit rows. ArtifactDiff.CompareTemplate now DiffChildren over native sources so Preview reports a NativeAlarmSources field change. Proven by an end-to-end flatten test: an instance native-alarm-source override that dangled pre-fix now resolves against the re-imported template source.
