- NavMenu: move Import Bundle out of the nested RequireDesign/RequireAdmin
double-gate into the top-level Admin section so an Admin-only user sees it
without needing the Design role; Export Bundle stays in the Design section.
- TransportImport: inject IAuditService + ScadaLinkDbContext; emit a
BundleImportUnlockFailed audit row (best-effort, swallowed on failure) on
every wrong-passphrase attempt in SubmitPassphraseAsync, with attempt
number and error reason in afterState.
- docker central-node-a/b appsettings: add ScadaLink:Transport section with
SourceEnvironment = "docker-cluster" so the importer picks up a non-null
environment name in the audit trail.
- CentralUI.Tests: register IAuditService mock + SQLite in-memory
ScadaLinkDbContext in TransportImportPageTests to satisfy the two new injects.
