Tab Navigation in Detail Pages

Detail pages for Account Holders, Payments, Incoming Payments, and Accounts have been reorganized using tabs. Instead of scrolling through a single long page, related information is now grouped and accessible at a glance — making it much easier to navigate between details, activity, and status without losing context. This new structure sets the foundation for how we'll continue organizing information across the Control Panel. Also, error details now appear as a tooltip inside the Status column — no separate column needed.
