ATLAS-5347: Fix Skeleton Loader stuck indefinitely in Administration Audit tab for Purge operations

When expanding the details for PURGE or AUTO_PURGE operations in the React UI Administration Audits tab, the skeleton loader would get stuck spinning indefinitely.

This patch fixes the issue by:

1. Explicitly passing loading={false} to <AuditsTab /> within AuditResults.tsx.
2. Updating the rendering condition in AttributeProperties.tsx to strictly check for loading === true rather than defaulting to the skeleton loader when loading is undefined.
3. Updating the corresponding Jest unit tests in AttributeProperties.test.tsx to match the new strict conditional rendering logic.

How was this patch tested?

• Manual Testing: Verified locally that expanding PURGE and AUTO_PURGE operations in the Administration Audits UI successfully loads the data without freezing the skeleton loader.
• Unit Tests: Updated and successfully ran Jest unit tests (AttributeProperties.test.tsx) to verify that the loader disappears correctly when entity data is available and loading is not explicitly set to true.
