Low-severity review nits, no behaviour change to the happy path:
- CloseModals() now also resets the leftover _*ModalIsNew / parent-id fields
(area ClusterId, line AreaId, equipment LineId, tag/vtag) for symmetry —
harmless today (always set before a modal opens) but consistent.
- HandleAddChild / HandleAddVirtualTag / HandleEdit gain a _modalBusy guard
(try/finally) so a rapid double-action can't race two service loads into the
same modal state. The switch bodies are re-indented under the try block.
- VirtualTagModal DataType is now an InputSelect over the standard OPC UA type
list (the same set TagModal uses) instead of free-text InputText.
- RefreshEquipmentChildrenAsync documents that callers own StateHasChanged()
and the full-reload fallback is spelled out as a block with a comment.
Build clean; AdminUI.Tests 216/216.
GlobalUns passed string component params without an @ prefix
(Filter="_filter", ClusterId="_areaModalClusterId", etc.). Razor treats a
string-typed component-parameter value without @ as a LITERAL, so UnsTree.Filter
became the literal "_filter" and the modals received literal field-name strings
as their parent ids. The non-empty literal filter matched no node, so the tree
never rendered children beyond the enterprise roots; the modals would have created
children under a bogus cluster/area/line/equipment id.
Add @ to the six string-param bindings. Verified live in docker-dev: the full
Enterprise->Cluster->Area->Line->Equipment tree renders and an area created via the
modal persists with the correct ClusterId (MAIN). No unit test added — this is a
Razor binding issue not reachable without bUnit (not used in this project).
