Drift detection: explicitly mark unchecked resources as "not checked", rather than skip from results table

I think the existence of the warning

indicates a usability bug.

Should instead include all of a stack's resources in the drift results table, and mark those that Cloudformation's drift detection doesn't support with a "not checked" warning message.

For stacks with a very small number of resources, spotting which of a stack's resources aren't in the drift results table is easy, but this quickly becomes error prone as a stack has more resources.

### Other Details

_No response_

Start by reviewing the CloudFormation drift detection results table and the stack details page to understand how supported and unsupported resources are currently represented. Done means every stack resource appears in the drift results, with resources unsupported by drift detection clearly marked "not checked" rather than omitted.
