Subject: [PATCH] fix: improved error handling and optimized reactivity in
 Dashboard component
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Improvements & Fixes:
✅ Enhanced error handling for GraphQL queries & mutations:

Displays more informative error messages for debugging.
Ensures router.push(Path.Home) only triggers when necessary.
✅ Optimized useMemo usage for dashboardItems:
Prevents unnecessary re-renders when data structure remains the same.
✅ Wrapped onUpdateChange & onDelete in try-catch blocks:
Ensures UI does not break if an API call fails.
✅ Preserved all core logic – No functional changes, just refinements for stability.
