Fix timeout errors causing step history to be lost.

[samwho]

Description

If an automation times out, we never appended the step results to the automation results causing it to look like the automation didn't do anything. This PR fixes that by keeping track of intermediate results and using them if the automation times out.

Launchcontrol

No longer loses automation step history if the automation times out.

BUDI-9374 Trigger automation actions run asynchronously, and timeouts prevent all steps appearing in the automation history.

Pull Request Overview

This PR ensures intermediate automation step results are retained and returned when an automation run times out.

• Introduce a _stepResults buffer on AutomationContext and in Orchestrator to accumulate step outputs.
• Refactor timeout handling to use helpers.withTimeout and append buffered results after timeout.
• Add comprehensive tests for various timeout and nested-trigger scenarios.

• The code references helpers.withTimeout, but helpers is not imported. Add helpers to the import from @budibase/backend-core to avoid runtime errors.

import { context, logging, configs } from "@budibase/backend-core"

packages/server/src/threads/automation.ts:352

• Calling span.addTags without checking if span is defined may throw an error. Consider using span?.addTags or guarding against undefined.

span.addTags({ timeout: true })
