#05-T23. ArtifactDiff.CompareTemplate gains optional folderNameById /
templateNameById maps; FolderNameOf / BaseTemplateNameOf / CompositionTargetNameOf
resolve the existing template's FolderId / ParentTemplateId / composition
ComposedTemplateId to real names (falling back to the <id:N> placeholder only
when a map is absent or misses, keeping existing unit-test callers valid).
PreviewAsync builds templateNameById from GetAllTemplatesAsync (parent/composition
targets can be any template, not just bundle-named ones) and threads both maps
through. Fixes spurious Modified on every re-import of a foldered/derived/composed
template. End-to-end preview test + two ArtifactDiff unit tests.

New TemplateChildEquality is the one place "has this template child changed?" is
decided, comparing the COMPLETE writable field set per entity (attributes now incl.
ElementDataType + LockedInDerived; alarms incl. the on-trigger script by name +
LockedInDerived; scripts incl. MinTimeBetweenRuns/ExecutionTimeoutSeconds +
LockedInDerived; native sources per T5). ArtifactDiff.CompareTemplate and all four
BundleImporter.SyncTemplate*Async predicates now route through it — closing the
class of bug where Preview reported Identical for an artifact an Overwrite would
mutate. The attribute sync passes a value-normalised DTO so List-value re-imports
stay idempotent; the alarm on-trigger change now surfaces in both diff and sync.
