Summary

Fixes the issue where editing a cell in the Data Table only updates the edited field, leaving dependent columns like updated_at stale until page reload.

After a cell value change:

• Calls updateRow with the new data.
• Immediately fetches the full updated row via fetchRowById to get server-generated fields (e.g., new updatedAt timestamp).
• Replaces the local row in rowData with the fresh data.
• Triggers setGridData to refresh the AG Grid view.

This ensures the UI reflects backend changes without requiring a full page reload.
