Invalidate previously approved credentials

Product Suggestion
Add the ability to invalidate a credential that has previously been approved.

This would allow users to mark an approved credential as no longer valid if it was approved in error or if the submitted document is later found to be incorrect.

Problem Statement
Once a credential has been approved, it may continue to show as valid even if the approval was made by mistake.

This can create confusion where the correct credential is still outstanding, as the contractor may appear compliant when they still need to provide the right document.

Suggested Improvement
Add an option to invalidate or cancel a previously approved credential.

When invalidated, the credential should no longer count as valid, and the contractor should show as still needing to provide the correct credential.

Potential Benefits

Clearer credential status
Reduced risk of incorrect compliance records
Ability to correct approval mistakes
Better visibility of outstanding credentials
Improved control over contractor document approval
