Fields no longer exists in securityhub findings

As per https://docs.aws.amazon.com/securityhub/latest/userguide/controls-findings-create-update.html

_StandardsGuideArn or StandardsArn
The ARN of the standard associated with the control.

For the CIS AWS Foundations Benchmark standard, the field is StandardsGuideArn.

For PCI DSS and AWS Foundational Security Best Practices standards, the field is StandardsArn.

These fields are removed in favor of Compliance.AssociatedStandards if you enable [consolidated control findings](https://docs.aws.amazon.com/securityhub/latest/userguide/controls-findings-create-update.html#consolidated-control-findings)._

Start by locating where the dashboard processes Security Hub finding fields, especially StandardsGuideArn and StandardsArn. Compare that handling with Compliance.AssociatedStandards and the AWS documentation linked in the issue; done means findings using consolidated control findings are handled without relying on removed fields.
