feat(server): route OPC UA Part 9 shelve methods to ScriptedAlarmEngine (#24)

OneShotShelve / TimedShelve / Unshelve now reach the ScriptedAlarmEngine.
Scripted-alarm condition nodes get a ShelvedStateMachine subtree created
before alarm.Create so the stack wires each shelve method's dispatch
handler; AlarmConditionState.OnShelve / OnTimedUnshelve route to the
engine and mirror the result onto the OPC UA node via SetShelvingState.

The three per-instance shelve method NodeIds are indexed so the Call gate
resolves them to OpcUaOperation.AlarmShelve instead of falling through to
generic Call. Engine dispatch is split into the node-free InvokeEngineShelve
so the routing decision is unit-testable.

Adds 9 unit tests; updates phase-7-status.md Gap 1 (only AddComment remains
unwired) and the #24 entry in looseends.md.

These are real open items, not issues with the plan reconciliation.
### Gap 1 — OPC UA method-call dispatch for scripted alarm Ack/Confirm/Shelve (Stream G / C.6)
### Gap 1 — OPC UA method-call dispatch for scripted alarm AddComment (Stream G / C.6)
`DriverNodeManager.MethodCall` does not route OPC UA `Acknowledge` / `Confirm` / `OneShotShelve` / `TimedShelve` / `Unshelve` / `AddComment` method invocations to the `ScriptedAlarmEngine`. Operators can acknowledge scripted alarms through the Admin UI today; OPC UA HMI clients expecting to use Part 9 method nodes directly cannot. Explicit in `phase-7-e2e-smoke.md` §"Known limitations".
`Acknowledge` / `Confirm` route to the `ScriptedAlarmEngine` via `DriverNodeManager.RouteScriptedAlarmMethodCalls` (task #24). `OneShotShelve` / `TimedShelve` / `Unshelve` route via the native `AlarmConditionState.OnShelve` / `OnTimedUnshelve` hooks wired in `MarkAsAlarmCondition` (task #24 follow-up); the per-instance shelve method NodeIds are indexed so the Call gate resolves them to `OpcUaOperation.AlarmShelve`. Only `AddComment` is still not wired to the OPC UA method path — the engine has `AddCommentAsync` but no Part 9 `AddComment` method node is dispatched to it.
### Gap 2 — Admin UI: no `/virtual-tags` tab or form (Stream F.2)

# Loose ends
State as of 2026-05-18, after the #9#29 task-list run. Everything on the
formal task list is shipped except #20; the items below are what genuinely
remains, plus follow-ups surfaced during the run.
## Open task
- **#20 — D.1 dev-rig rollout smoke.** A full 3-service deployment
(gateway + worker + server + Wonderware historian sidecar): deploy the
refreshed binaries, run `scripts/install/Refresh-Services.ps1`, exercise
alarms end-to-end, and capture the rollout artifact. The code blockers
were cleared by #18; the act itself needs the physical AVEVA dev rig and
cannot be produced from a dev box. Runbook context in
`docs/plans/alarms-worker-wiring-plan.md`.
## Follow-ups surfaced during the run
- **C.1 live SDK binding.** `SdkAlarmHistorianWriteBackend.WriteBatchAsync`
(`src/Drivers/ZB.MOM.WW.OtOpcUa.Driver.Historian.Wonderware/Backend/`) is
still a placeholder returning `RetryPlease` for every event, so queued
alarm events are retained rather than written. Pinning the real
`aahClientManaged` alarm-write entry point is rig-gated — pairs with #20.
- **~~#24 Shelve-method routing.~~** DONE. Acknowledge / Confirm already
routed; OneShotShelve / TimedShelve / Unshelve now route via the native
`AlarmConditionState.OnShelve` / `OnTimedUnshelve` hooks wired in
`DriverNodeManager.MarkAsAlarmCondition` (scripted alarms get a shelvable
`ShelvedStateMachine` subtree created before `alarm.Create`). The three
per-instance shelve method NodeIds are indexed so the Call gate resolves
them to `OpcUaOperation.AlarmShelve`. Remaining: address-space
materialisation of the shelve method nodes is best confirmed by a live
OPC UA browse (pairs with the G6 / D.1 rig steps). `AddComment` is still
not wired to an OPC UA method node — see `phase-7-status.md` Gap 1.
- **mxaccessgw alarm epic branch.** The alarm subsystem work (A.2/A.3/A.4
+ the two production-gap fixes from #18) lives on the mxaccessgw branch
`docs/alarm-client-wm-app-finding`. It is NOT merged to mxaccessgw's main.
Whether/when to merge the alarm epic to main is an open release decision.
- **#15 operator/lab GA gates.** Two v2 GA gates are manual lab steps, not
automatable here: the OPC UA CTT (Compliance Test Tool) pass and the
deployment-checklist signoff. Documented in
`docs/plans/v2-ga-lab-gates-plan.md`.
## Done — for reference
The 5 Phase 7 gaps discovered mid-run (#24#28) were all completed and
merged; no Phase 7 gaps remain open. Add any new follow-ups above as they
are spun out.
