Pull request overview

This PR enhances the System Application’s Table Information experience by extending page 8704 “Indexes List Part” to surface more index/SIFT details, add visual indicators for index health, and add safeguards against disrupting SIFT-related indexes (per issue #6856).

Changes:

• Adds new index insight columns (Index Fields, Included Columns, Maintain SIFT, SIFT Fields, Reads/Writes ratio) and reorders/freezes key identification columns.
• Introduces visual styling to highlight disabled indexes and high fragmentation.
• Improves usability by blanking “Last seek/scan/lookup/update” timestamps when there’s no corresponding activity, and adds a guard to prevent disabling SIFT-maintained indexes.

Would be great if you could post a screenshot of how good your page looks, that makes it easier for others to evaluate if it is a good change.

I will merge #6782 this tomorrow, then lets get this one in afterwards.
