Pull request overview

This PR (OPS-4065) updates the EC2 “Get Instances” implementation to optionally tolerate per-region failures and still return results from successful regions, enabling workflows to proceed with partial data.

Changes:

• Added getEc2InstancesWithPartialResults helper that returns { results, failedRegions } using Promise.allSettled across regions.
• Added allowPartialResults checkbox to the EC2 Get Instances block action to switch between strict vs partial-result behavior.
• Added/updated unit tests covering partial results behavior and action output shape.

Moved the common logic here to remove duplication between the partial-results and strict branches. This function builds the list of EC2 describe batches
