Rework ScriptRuntimeContext.ExternalSystem.CachedCall to fit the M3 combined-telemetry model: * Mints a fresh TrackedOperationId and emits one CachedSubmit packet via ICachedCallTelemetryForwarder BEFORE handing the call off — the SiteCalls row is materialised before the first delivery attempt so Tracking.Status(id) can observe a Submitted row even if immediate delivery resolves before the helper returns. * Threads the TrackedOperationId into IExternalSystemClient.CachedCallAsync as a new optional parameter (and into IDatabaseGateway.CachedWriteAsync for the Database mirror set up here for E6). The gateway uses the id as the StoreAndForward messageId so the retry loop (Tasks E4/E5) can recover it from StoreAndForwardMessage.Id. * Returns the TrackedOperationId rather than ExternalCallResult — the script's contract is now "get a tracking handle, observe outcome via Tracking.Status". Best-effort emission: a thrown forwarder is logged + swallowed; the original call still runs and the id is still returned. DatabaseHelper gets the matching siteId / sourceScript / forwarder fields and a parallel CachedSubmit emitter (Channel=DbOutbound) so Task E6's Database.CachedWrite mirror plugs in without further runtime wiring. New ICachedCallTelemetryForwarder seam in Commons.Interfaces.Services so SiteRuntime depends on Commons (existing arrow) rather than ScadaLink.AuditLog (would have introduced a new dependency). Bundle E task E3 (and helper-shape work for E6).
