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.
