Add DataType? ElementDataType to TemplateAttributeDto (optional, default null
for backward-compat with old bundles). Map it in both directions in
EntitySerializer (export + FromBundleContent) and in all three
TemplateAttribute construction sites in BundleImporter (BuildTemplate,
SyncTemplateAttributesAsync add-path, and SyncTemplateAttributesAsync
update-path including change-detection). Two new round-trip tests in
EntitySerializerTests confirm List attributes survive export→import and that
old DTOs with null ElementDataType import cleanly.
Renames the 13 SCADALINK_* runtime env vars → SCADABRIDGE_*, the ScadaLink__
.NET config keys → ScadaBridge__, the stale ScadaLink.Host.exe assembly name
→ ZB.MOM.WW.ScadaBridge.Host.exe, the scadalink_app SQL login → scadabridge_app,
and residual identifiers/comments/docs. Migration records (prior rename
tooling/design, DB-rename helper, this scrub script) carved out.
Adds tools/scrub-scadalink-refs.sh.
