Joseph Doherty d2f3a243cd Phase 6.1 Stream A.3 — wrap all 4 HistoryRead dispatch paths through CapabilityInvoker ...

Per Stream A.3 coverage goal, every IHistoryProvider method on the server
dispatch surface routes through the invoker with DriverCapability.HistoryRead:
- HistoryReadRaw  (line 487)
- HistoryReadProcessed  (line 551)
- HistoryReadAtTime  (line 608)
- HistoryReadEvents  (line 665)

Each gets timeout + per-(driver, host) circuit breaker + the default Tier
retry policy (Tier A default: 2 retries at 30s timeout). Inner driver
GetAwaiter().GetResult() pattern preserved because the OPC UA stack's
HistoryRead hook is sync-returning-void — see CustomNodeManager2.

With Read, Write, and HistoryRead wrapped, Stream A's invoker-coverage
compliance check passes for the dispatch surfaces that live in
DriverNodeManager. Subscribe / AlarmSubscribe / AlarmAcknowledge sit behind
push-based subscription plumbing (driver → OPC UA event layer) rather than
server-pull dispatch, so they're wrapped in the driver-to-server glue rather
than in DriverNodeManager — deferred to the follow-up PR that wires the
remaining capability surfaces per the final Roslyn-analyzer-enforced coverage
map.

Full solution dotnet test: 948 passing. Pre-existing Client.CLI Subscribe
flake unchanged.
